Optional warnings are enabled by using the ----wwww switch.
Warnings may be captured by setting $$$$^^^^QQQQ to a reference to
a routine that will be called on each warning instead of
printing it. See the _p_e_r_l_v_a_r manpage. Trappable errors
may be trapped using the eval operator. See the eeeevvvvaaaallll
entry in the _p_e_r_l_f_u_n_c manpage.
Some of these messages are generic. Spots that vary are
denoted with a %%%%ssss, just as in a printf format. Note that
some message start with a %%%%ssss! The symbols """"%%%%----????@@@@ sort
before the letters, while [[[[ and \\\\ sort after.
"my" variable %s can't be in a package
(F) Lexically scoped variables aren't in a package, so
it doesn't make sense to try to declare one with a
package qualifier on the front. Use _l_o_c_a_l_(_) if you
want to localize a package variable.
"no" not allowed in expression
(F) The "no" keyword is recognized and executed at
compile time, and returns no useful value. See the
_p_e_r_l_m_o_d manpage.
"use" not allowed in expression
(F) The "use" keyword is recognized and executed at
compile time, and returns no useful value. See the
_p_e_r_l_m_o_d manpage.
% may only be used in unpack
(F) You can't pack a string by supplying a checksum,
since the checksumming process loses information, and
you can't go the other way. See the uuuunnnnppppaaaacccckkkk entry in
the _p_e_r_l_f_u_n_c manpage.
%s (...) interpreted as function
(W) You've run afoul of the rule that says that any
list operator followed by parentheses turns into a
function, with all the list operators arguments found
inside the parens. See the section on _T_e_r_m_s _a_n_d _L_i_s_t
27/Feb/96 perl 5.002 with 1
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
_O_p_e_r_a_t_o_r_s _(_L_e_f_t_w_a_r_d_) in the _p_e_r_l_o_p manpage.
%s argument is not a HASH element
(F) The argument to _d_e_l_e_t_e_(_) or _e_x_i_s_t_s_(_) must be a
hash element, such as
$$$$ffffoooooooo{{{{$$$$bbbbaaaarrrr}}}}
$$$$rrrreeeeffff---->>>>[[[[11112222]]]]---->>>>{{{{""""ssssuuuussssiiiieeee""""}}}}
%s did not return a true value
(F) A required (or used) file must return a true value
to indicate that it compiled correctly and ran its
initialization code correctly. It's traditional to
end such a file with a "1;", though any true value
would do. See the rrrreeeeqqqquuuuiiiirrrreeee entry in the _p_e_r_l_f_u_n_c
manpage.
%s found where operator expected
(S) The Perl lexer knows whether to expect a term or
an operator. If it sees what it knows to be a term
when it was expecting to see an operator, it gives you
this warning. Usually it indicates that an operator
or delimiter was omitted, such as a semicolon.
%s had compilation errors.
(F) The final summary message when a ppppeeeerrrrllll ----cccc fails.
%s has too many errors.
(F) The parser has given up trying to parse the
program after 10 errors. Further error messages would
likely be uninformative.
%s matches null string many times
(W) The pattern you've specified would be an infinite
loop if the regular expression engine didn't
specifically check for that. See the _p_e_r_l_r_e manpage.
%s never introduced
(S) The symbol in question was declared but somehow
went out of scope before it could possibly have been
used.
%s syntax OK
(F) The final summary message when a ppppeeeerrrrllll ----cccc succeeds.
%s: Command not found.
(A) You've accidentally run your script through ccccsssshhhh
instead of Perl. Check the <#!> line, or manually
feed your script into Perl yourself.
%s: Expression syntax.
(A) You've accidentally run your script through ccccsssshhhh
instead of Perl. Check the <#!> line, or manually
27/Feb/96 perl 5.002 with 2
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
feed your script into Perl yourself.
%s: Undefined variable.
(A) You've accidentally run your script through ccccsssshhhh
instead of Perl. Check the <#!> line, or manually
feed your script into Perl yourself.
%s: not found
(A) You've accidentally run your script through the
Bourne shell instead of Perl. Check the <#!> line, or
manually feed your script into Perl yourself.
----PPPP not allowed for setuid/setgid script
(F) The script would have to be opened by the C
preprocessor by name, which provides a race condition
that breaks security.
----TTTT and ----BBBB not implemented on filehandles
(F) Perl can't peek at the stdio buffer of filehandles
when it doesn't know about your kind of stdio. You'll
have to use a filename instead.
500 Server error
See Server error.
?+* follows nothing in regexp
(F) You started a regular expression with a
quantifier. Backslash it if you meant it literally.
See the _p_e_r_l_r_e manpage.
@ outside of string
(F) You had a pack template that specified an
absolution position outside the string being unpacked.
See the ppppaaaacccckkkk entry in the _p_e_r_l_f_u_n_c manpage.
accept() on closed fd
(W) You tried to do an accept on a closed socket. Did
you forget to check the return value of your _s_o_c_k_e_t_(_)
call? See the aaaacccccccceeeepppptttt entry in the _p_e_r_l_f_u_n_c manpage.
Allocation too large: %lx
(F) You can't allocate more than 64K on an MSDOS
machine.
Arg too short for msgsnd
(F) _m_s_g_s_n_d_(_) requires a string at least as long as
_s_i_z_e_o_f(long).
Ambiguous use of %s resolved as %s
(W)(S) You said something that may not be interpreted
the way you thought. Normally it's pretty easy to
disambiguate it by supplying a missing quote,
operator, paren pair or declaration.
27/Feb/96 perl 5.002 with 3
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
Args must match #! line
(F) The setuid emulator requires that the arguments
Perl was invoked with match the arguments specified on
the #! line.
Argument "%s" isn't numeric
(W) The indicated string was fed as an argument to an
operator that expected a numeric value instead. If
you're fortunate the message will identify which
operator was so unfortunate.
Array @%s missing the @ in argument %d of %s()
(D) Really old Perl let you omit the @ on array names
in some spots. This is now heavily deprecated.
assertion botched: %s
(P) The malloc package that comes with Perl had an
internal failure.
Assertion failed: file "%s"
(P) A general assertion failed. The file in question
must be examined.
Assignment to both a list and a scalar
(F) If you assign to a conditional operator, the 2nd
and 3rd arguments must either both be scalars or both
be lists. Otherwise Perl won't know which context to
supply to the right side.
Attempt to free non-arena SV: 0x%lx
(P) All SV objects are supposed to be allocated from
arenas that will be garbage collected on exit. An SV
was discovered to be outside any of those arenas.
Attempt to free temp prematurely
(W) Mortalized values are supposed to be freed by the
_f_r_e_e___t_m_p_s_(_) routine. This indicates that something
else is freeing the SV before the _f_r_e_e___t_m_p_s_(_) routine
gets a chance, which means that the _f_r_e_e___t_m_p_s_(_)
routine will be freeing an unreferenced scalar when it
does try to free it.
Attempt to free unreferenced glob pointers
(P) The reference counts got screwed up on symbol
aliases.
Attempt to free unreferenced scalar
(W) Perl went to decrement the reference count of a
scalar to see if it would go to 0, and discovered that
it had already gone to 0 earlier, and should have been
freed, and in fact, probably was freed. This could
indicate that _S_v_R_E_F_C_N_T___d_e_c_(_) was called too many
times, or that _S_v_R_E_F_C_N_T___i_n_c_(_) was called too few
times, or that the SV was mortalized when it shouldn't
27/Feb/96 perl 5.002 with 4
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
have been, or that memory has been corrupted.
Bad arg length for %s, is %d, should be %d
(F) You passed a buffer of the wrong size to one of
_m_s_g_c_t_l_(_), _s_e_m_c_t_l_(_) or _s_h_m_c_t_l_(_). In C parlance, the
correct sized are, respectively,
sizeof(struct msqid_ds *), sizeof(struct semid_ds *)
and sizeof(struct shmid_ds *).
Bad associative array
(P) One of the internal hash routines was passed a
null HV pointer.
Bad filehandle: %s
(F) A symbol was passed to something wanting a
filehandle, but the symbol has no filehandle
associated with it. Perhaps you didn't do an _o_p_e_n_(_),
or did it in another package.
Bad free() ignored
(S) An internal routine called _f_r_e_e_(_) on something
that had never been _m_a_l_l_o_c_(_)ed in the first place.
Bad name after %s::
(F) You started to name a symbol by using a package
prefix, and then didn't finish the symbol. In
particular, you can't interpolate outside of quotes,
so
$$$$vvvvaaaarrrr ==== ''''mmmmyyyyvvvvaaaarrrr'''';;;;
$$$$ssssyyyymmmm ==== mmmmyyyyppppaaaacccckkkk::::::::$$$$vvvvaaaarrrr;;;;
is not the same as
$$$$vvvvaaaarrrr ==== ''''mmmmyyyyvvvvaaaarrrr'''';;;;
$$$$ssssyyyymmmm ==== """"mmmmyyyyppppaaaacccckkkk::::::::$$$$vvvvaaaarrrr"""";;;;
Bad symbol for array
(P) An internal request asked to add an array entry to
something that wasn't a symbol table entry.
Bad symbol for filehandle
(P) An internal request asked to add a filehandle
entry to something that wasn't a symbol table entry.
Bad symbol for hash
(P) An internal request asked to add a hash entry to
something that wasn't a symbol table entry.
Badly places ()'s
(A) You've accidentally run your script through ccccsssshhhh
instead of Perl. Check the <#!> line, or manually
feed your script into Perl yourself.
27/Feb/96 perl 5.002 with 5
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
BEGIN failed--compilation aborted
(F) An untrapped exception was raised while executing
a BEGIN subroutine. Compilation stops immediately and
the interpreter is exited.
bind() on closed fd
(W) You tried to do a bind on a closed socket. Did
you forget to check the return value of your _s_o_c_k_e_t_(_)
call? See the bbbbiiiinnnndddd entry in the _p_e_r_l_f_u_n_c manpage.
Bizarre copy of %s in %s
(P) Perl detected an attempt to copy an internal value
that is not copiable.
Callback called exit
(F) A subroutine invoked from an external package via
_p_e_r_l___c_a_l_l___s_v_(_) exited by calling exit.
Can't "last" outside a block
(F) A "last" statement was executed to break out of
the current block, except that there's this itty bitty
problem called there isn't a current block. Note that
an "if" or "else" block doesn't count as a "loopish"
block. You can usually double the curlies to get the
same effect though, since the inner curlies will be
considered a block that loops once. See the llllaaaasssstttt
entry in the _p_e_r_l_f_u_n_c manpage.
Can't "next" outside a block
(F) A "next" statement was executed to reiterate the
current block, but there isn't a current block. Note
that an "if" or "else" block doesn't count as a
"loopish" block. You can usually double the curlies
to get the same effect though, since the inner curlies
will be considered a block that loops once. See the
llllaaaasssstttt entry in the _p_e_r_l_f_u_n_c manpage.
Can't "redo" outside a block
(F) A "redo" statement was executed to restart the
current block, but there isn't a current block. Note
that an "if" or "else" block doesn't count as a
"loopish" block. You can usually double the curlies
to get the same effect though, since the inner curlies
will be considered a block that loops once. See the
llllaaaasssstttt entry in the _p_e_r_l_f_u_n_c manpage.
Can't bless non-reference value
(F) Only hard references may be blessed. This is how
Perl "enforces" encapsulation of objects. See the
_p_e_r_l_o_b_j manpage.
Can't break at that line
(S) A warning intended for while running within the
debugger, indicating the line number specified wasn't
27/Feb/96 perl 5.002 with 6
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
the location of a statement that could be stopped at.
Can't call method "%s" in empty package "%s"
(F) You called a method correctly, and it correctly
indicated a package functioning as a class, but that
package doesn't have ANYTHING defined in it, let alone
methods. See the _p_e_r_l_o_b_j manpage.
Can't call method "%s" on unblessed reference
(F) A method call must know what package it's supposed
to run in. It ordinarily finds this out from the
object reference you supply, but you didn't supply an
object reference in this case. A reference isn't an
object reference until it has been blessed. See the
_p_e_r_l_o_b_j manpage.
Can't call method "%s" without a package or object
reference
(F) You used the syntax of a method call, but the slot
filled by the object reference or package name
contains an expression that returns neither an object
reference nor a package name. (Perhaps it's null?)
Something like this will reproduce the error:
$$$$BBBBAAAADDDDRRRREEEEFFFF ==== uuuunnnnddddeeeeffff;;;;
pppprrrroooocccceeeessssssss $$$$BBBBAAAADDDDRRRREEEEFFFF 1111,,,,2222,,,,3333;;;;
$$$$BBBBAAAADDDDRRRREEEEFFFF---->>>>pppprrrroooocccceeeessssssss((((1111,,,,2222,,,,3333))));;;;
Can't chdir to %s
(F) You called ppppeeeerrrrllll ----xxxx////ffffoooooooo////bbbbaaaarrrr, but ////ffffoooooooo////bbbbaaaarrrr is not a
directory that you can chdir to, possibly because it
doesn't exist.
Can't coerce %s to integer in %s
(F) Certain types of SVs, in particular real symbol
table entries (type GLOB), can't be forced to stop
being what they are. So you can't say things like:
****ffffoooooooo ++++==== 1111;;;;
You CAN say
$$$$ffffoooooooo ==== ****ffffoooooooo;;;;
$$$$ffffoooooooo ++++==== 1111;;;;
but then $$$$ffffoooooooo no longer contains a glob.
Can't coerce %s to number in %s
(F) Certain types of SVs, in particular real symbol
table entries (type GLOB), can't be forced to stop
being what they are.
27/Feb/96 perl 5.002 with 7
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
Can't coerce %s to string in %s
(F) Certain types of SVs, in particular real symbol
table entries (type GLOB), can't be forced to stop
being what they are.
Can't create pipe mailbox
(P) An error peculiar to VMS. The process is
suffering from exhausted quotas or other plumbing
problems.
Can't declare %s in my
(F) Only scalar, array and hash variables may be
declared as lexical variables. They must have
ordinary identifiers as names.
Can't do inplace edit on %s: %s
(S) The creation of the new file failed for the
indicated reason.
Can't do inplace edit without backup
(F) You're on a system such as MSDOS that gets
confused if you try reading from a deleted (but still
opened) file. You have to say ----iiii....bbbbaaaakkkk, or some such.
Can't do inplace edit: %s > 14 characters
(S) There isn't enough room in the filename to make a
backup name for the file.
Can't do inplace edit: %s is not a regular file
(S) You tried to use the ----iiii switch on a special file,
such as a file in /dev, or a FIFO. The file was
ignored.
Can't do setegid!
(P) The _s_e_t_e_g_i_d_(_) call failed for some reason in the
setuid emulator of suidperl.
Can't do seteuid!
(P) The setuid emulator of suidperl failed for some
reason.
Can't do setuid
(F) This typically means that ordinary perl tried to
exec suidperl to do setuid emulation, but couldn't
exec it. It looks for a name of the form sperl5.000
in the same directory that the perl executable resides
under the name perl5.000, typically /usr/local/bin on
Unix machines. If the file is there, check the
execute permissions. If it isn't, ask your sysadmin
why he and/or she removed it.
Can't do waitpid with flags
(F) This machine doesn't have either _w_a_i_t_p_i_d_(_) or
_w_a_i_t_4_(_), so only _w_a_i_t_p_i_d_(_) without flags is emulated.
27/Feb/96 perl 5.002 with 8
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
Can't do {n,m} with n > m
(F) Minima must be less than or equal to maxima. If
you really want your regexp to match something 0
times, just put {0}. See the _p_e_r_l_r_e manpage.
Can't emulate -%s on #! line
(F) The #! line specifies a switch that doesn't make
sense at this point. For example, it'd be kind of
silly to put a ----xxxx on the #! line.
Can't exec "%s": %s
(W) An _s_y_s_t_e_m_(_), _e_x_e_c_(_) or piped open call could not
execute the named program for the indicated reason.
Typical reasons include: the permissions were wrong on
the file, the file wasn't found in $$$$EEEENNNNVVVV{{{{PPPPAAAATTTTHHHH}}}}, the
executable in question was compiled for another
architecture, or the #! line in a script points to an
interpreter that can't be run for similar reasons.
(Or maybe your system doesn't support #! at all.)
Can't exec %s
(F) Perl was trying to execute the indicated program
for you because that's what the #! line said. If
that's not what you wanted, you may need to mention
"perl" on the #! line somewhere.
Can't execute %s
(F) You used the ----SSSS switch, but the script to execute
could not be found in the PATH, or at least not with
the correct permissions.
Can't find label %s
(F) You said to goto a label that isn't mentioned
anywhere that it's possible for us to go to. See the
ggggoooottttoooo entry in the _p_e_r_l_f_u_n_c manpage.
Can't find string terminator %s anywhere before EOF
(F) Perl strings can stretch over multiple lines.
This message means that the closing delimiter was
omitted. Since bracketed quotes count nesting levels,
the following is missing its final parenthesis:
pppprrrriiiinnnntttt qqqq((((TTTThhhheeee cccchhhhaaaarrrraaaacccctttteeeerrrr ''''(((('''' ssssttttaaaarrrrttttssss aaaa ssssiiiiddddeeee ccccoooommmmmmmmeeeennnntttt....))))
Can't fork
(F) A fatal error occurred while trying to fork while
opening a pipeline.
Can't get filespec - stale stat buffer?
(S) A warning peculiar to VMS. This arises because of
the difference between access checks under VMS and
under the Unix model Perl assumes. Under VMS, access
checks are done by filename, rather than by bits in
27/Feb/96 perl 5.002 with 9
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
the stat buffer, so that ACLs and other protections
can be taken into account. Unfortunately, Perl
assumes that the stat buffer contains all the
necessary information, and passes it, instead of the
filespec, to the access checking routine. It will try
to retrieve the filespec using the device name and FID
present in the stat buffer, but this works only if you
haven't made a subsequent call to the CRTL _s_t_a_t_(_)
routine, since the device name is overwritten with
each call. If this warning appears, the name lookup
failed, and the access checking routine gave up and
returned FALSE, just to be conservative. (Note: The
access checking routine knows about the Perl ssssttttaaaatttt
operator and file tests, so you shouldn't ever see
this warning in response to a Perl command; it arises
only if some internal code takes stat buffers
lightly.)
Can't get pipe mailbox device name
(P) An error peculiar to VMS. After creating a
mailbox to act as a pipe, Perl can't retrieve its name
for later use.
Can't get SYSGEN parameter value for MAXBUF
(P) An error peculiar to VMS. Perl asked $$$$GGGGEEEETTTTSSSSYYYYIIII how
big you want your mailbox buffers to be, and didn't
get an answer.
Can't goto subroutine outside a subroutine
(F) The deeply magical "goto subroutine" call can only
replace one subroutine call for another. It can't
manufacture one out of whole cloth. In general you
should only be calling it out of an AUTOLOAD routine
anyway. See the ggggoooottttoooo entry in the _p_e_r_l_f_u_n_c manpage.
Can't localize a reference
(F) You said something like llllooooccccaaaallll $$$$$$$$rrrreeeeffff, which is not
allowed because the compiler can't determine whether
$$$$rrrreeeeffff will end up pointing to anything with a symbol
table entry, and a symbol table entry is necessary to
do a local.
Can't localize lexical variable %s
(F) You used local on a variable name that was
previous declared as a lexical variable using "my".
This is not allowed. If you want to localize a
package variable of the same name, qualify it with the
package name.
Can't locate %s in @INC
(F) You said to do (or require, or use) a file that
couldn't be found in any of the libraries mentioned in
@@@@IIIINNNNCCCC. Perhaps you need to set the PERL5LIB
environment variable to say where the extra library
27/Feb/96 perl 5.002 with 10
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
is, or maybe the script needs to add the library name
to @@@@IIIINNNNCCCC. Or maybe you just misspelled the name of the
file. See the rrrreeeeqqqquuuuiiiirrrreeee entry in the _p_e_r_l_f_u_n_c manpage.
Can't locate object method "%s" via package "%s"
(F) You called a method correctly, and it correctly
indicated a package functioning as a class, but that
package doesn't define that particular method, nor
does any of it's base classes. See the _p_e_r_l_o_b_j
manpage.
Can't locate package %s for @%s::ISA
(W) The @@@@IIIISSSSAAAA array contained the name of another
package that doesn't seem to exist.
Can't mktemp()
(F) The _m_k_t_e_m_p_(_) routine failed for some reason while
trying to process a ----eeee switch. Maybe your /tmp
partition is full, or clobbered.
Can't modify %s in %s
(F) You aren't allowed to assign to the item
indicated, or otherwise try to change it, such as with
an autoincrement.
Can't modify non-existent substring
(P) The internal routine that does assignment to a
_s_u_b_s_t_r_(_) was handed a NULL.
Can't msgrcv to readonly var
(F) The target of a msgrcv must be modifiable in order
to be used as a receive buffer.
Can't open %s: %s
(S) An inplace edit couldn't open the original file
for the indicated reason. Usually this is because you
don't have read permission for the file.
Can't open bidirectional pipe
(W) You tried to say ooooppppeeeennnn((((CCCCMMMMDDDD,,,, """"||||ccccmmmmdddd||||"""")))), which is not
supported. You can try any of several modules in the
Perl library to do this, such as "open2.pl".
Alternately, direct the pipe's output to a file using
">", and then read it in under a different file
handle.
Can't open error file %s as stderr
(F) An error peculiar to VMS. Perl does its own
command line redirection, and couldn't open the file
specified after '2>' or '2>>' on the command line for
writing.
Can't open input file %s as stdin
(F) An error peculiar to VMS. Perl does its own
27/Feb/96 perl 5.002 with 11
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
command line redirection, and couldn't open the file
specified after '<' on the command line for reading.
Can't open output file %s as stdout
(F) An error peculiar to VMS. Perl does its own
command line redirection, and couldn't open the file
specified after '>' or '>>' on the command line for
writing.
Can't open output pipe (name: %s)
(P) An error peculiar to VMS. Perl does its own
command line redirection, and couldn't open the pipe
into which to send data destined for stdout.
Can't open perl script "%s": %s
(F) The script you specified can't be opened for the
indicated reason.
Can't rename %s to %s: %s, skipping file
(S) The rename done by the ----iiii switch failed for some
reason, probably because you don't have write
permission to the directory.
Can't reopen input pipe (name: %s) in binary mode
(P) An error peculiar to VMS. Perl thought stdin was
a pipe, and tried to reopen it to accept binary data.
Alas, it failed.
Can't reswap uid and euid
(P) The _s_e_t_r_e_u_i_d_(_) call failed for some reason in the
setuid emulator of suidperl.
Can't return outside a subroutine
(F) The return statement was executed in mainline
code, that is, where there was no subroutine call to
return out of. See the _p_e_r_l_s_u_b manpage.
Can't stat script "%s"
(P) For some reason you can't _f_s_t_a_t_(_) the script even
though you have it open already. Bizarre.
Can't swap uid and euid
(P) The _s_e_t_r_e_u_i_d_(_) call failed for some reason in the
setuid emulator of suidperl.
Can't take log of %g
(F) Logarithms are only defined on positive real
numbers.
Can't take sqrt of %g
(F) For ordinary real numbers, you can't take the
square root of a negative number. There's a Complex
package available for Perl, though, if you really want
to do that.

PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
Can't undef active subroutine
(F) You can't undefine a routine that's currently
running. You can, however, redefine it while it's
running, and you can even undef the redefined
subroutine while the old routine is running. Go
figure.
Can't unshift
(F) You tried to unshift an "unreal" array that can't
be unshifted, such as the main Perl stack.
Can't upgrade that kind of scalar
(P) The internal sv_upgrade routine adds "members" to
an SV, making it into a more specialized kind of SV.
The top several SV types are so specialized, however,
that they cannot be interconverted. This message
indicates that such a conversion was attempted.
Can't upgrade to undef
(P) The undefined SV is the bottom of the totem pole,
in the scheme of upgradability. Upgrading to undef
indicates an error in the code calling sv_upgrade.
Can't use "my %s" in sort comparison
(F) The global variables $$$$aaaa and $$$$bbbb are reserved for
sort comparisons. You mentioned $$$$aaaa or $$$$bbbb in the same
line as the <=> or cmp operator, and the variable had
earlier been declared as a lexical variable. Either
qualify the sort variable with the package name, or
rename the lexical variable.
Can't use %s for loop variable
(F) Only a simple scalar variable may be used as a
loop variable on a foreach.
Can't use %s ref as %s ref
(F) You've mixed up your reference types. You have to
dereference a reference of the type needed. You can
use the _r_e_f_(_) function to test the type of the
reference, if need be.
Can't use \1 to mean $1 in expression
(W) In an ordinary expression, backslash is a unary
operator that creates a reference to its argument.
The use of backslash to indicate a backreference to a
matched substring is only valid as part of a regular
expression pattern. Trying to do this in ordinary
Perl code produces a value that prints out looking
like _S_C_A_L_A_R(0xdecaf). Use the $$$$1111 form instead.
Can't use string ("%s") as %s ref while "strict refs" in
use
(F) Only hard references are allowed by "strict refs".
Symbolic references are disallowed. See the _p_e_r_l_r_e_f
27/Feb/96 perl 5.002 with 13
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
manpage.
Can't use an undefined value as %s reference
(F) A value used as either a hard reference or a
symbolic reference must be a defined value. This
helps to de-lurk some insidious errors.
Can't use delimiter brackets within expression
(F) The ${name} construct is for disambiguating
identifiers in strings, not in ordinary code.
Can't use global %s in "my"
(F) You tried to declare a magical variable as a
lexical variable. This is not allowed, because the
magic can only be tied to one location (namely the
global variable) and it would be incredibly confusing
to have variables in your program that looked like
magical variables but weren't.
Can't use subscript on %s
(F) The compiler tried to interpret a bracketed
expression as a subscript. But to the left of the
brackets was an expression that didn't look like an
array reference, or anything else subscriptable.
Can't write to temp file for ----eeee: %s
(F) The write routine failed for some reason while
trying to process a ----eeee switch. Maybe your /tmp
partition is full, or clobbered.
Can't x= to readonly value
(F) You tried to repeat a constant value (often the
undefined value) with an assignment operator, which
implies modifying the value itself. Perhaps you need
to copy the value to a temporary, and repeat that.
Cannot open temporary file
(F) The create routine failed for some reaon while
trying to process a ----eeee switch. Maybe your /tmp
partition is full, or clobbered.
chmod: mode argument is missing initial 0
(W) A novice will sometimes say
cccchhhhmmmmoooodddd 777777777777,,,, $$$$ffffiiiilllleeeennnnaaaammmmeeee
not realizing that 777 will be interpreted as a
decimal number, equivalent to 01411. Octal constants
are introduced with a leading 0 in Perl, as in C.
Close on unopened file <%s>
(W) You tried to close a filehandle that was never
opened.
27/Feb/96 perl 5.002 with 14
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
connect() on closed fd
(W) You tried to do a connect on a closed socket. Did
you forget to check the return value of your _s_o_c_k_e_t_(_)
call? See the ccccoooonnnnnnnneeeecccctttt entry in the _p_e_r_l_f_u_n_c manpage.
Corrupt malloc ptr 0x%lx at 0x%lx
(P) The malloc package that comes with Perl had an
internal failure.
corrupted regexp pointers
(P) The regular expression engine got confused by what
the regular expression compiler gave it.
corrupted regexp program
(P) The regular expression engine got passed a regexp
program without a valid magic number.
Deep recursion on subroutine "%s"
(W) This subroutine has called itself (directly or
indirectly) 100 times than it has returned. This
probably indicates an infinite recursion, unless
you're writing strange benchmark programs, in which
case it indicates something else.
Did you mean &%s instead?
(W) You probably referred to an imported subroutine
&FOO as $$$$FFFFOOOOOOOO or some such.
Did you mean $ or @ instead of %?
(W) You probably said %%%%hhhhaaaasssshhhh{$key} when you meant
$$$$hhhhaaaasssshhhh{$key} or @@@@hhhhaaaasssshhhh{@keys}. On the other hand, maybe
you just meant %%%%hhhhaaaasssshhhh and got carried away.
Do you need to predeclare %s?
(S) This is an educated guess made in conjunction with
the message "%s found where operator expected". It
often means a subroutine or module name is being
referenced that hasn't been declared yet. This may be
because of ordering problems in your file, or because
of a missing "sub", "package", "require", or "use"
statement. If you're referencing something that isn't
defined yet, you don't actually have to define the
subroutine or package before the current location.
You can use an empty "sub foo;" or "package FOO;" to
enter a "forward" declaration.
Don't know how to handle magic of type '%s'
(P) The internal handling of magical variables has
been cursed.
do_study: out of memory
(P) This should have been caught by _s_a_f_e_m_a_l_l_o_c_(_)
instead.
27/Feb/96 perl 5.002 with 15
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
Duplicate free() ignored
(S) An internal routine called _f_r_e_e_(_) on something
that had already been freed.
elseif should be elsif
(S) There is no keyword "elseif" in Perl because Larry
thinks it's ugly. Your code will be interpreted as an
attempt to call a method named "elseif" for the class
returned by the following block. This is unlikely to
be what you want.
END failed--cleanup aborted
(F) An untrapped exception was raised while executing
an END subroutine. The interpreter is immediately
exited.
Error converting file specification %s
(F) An error peculiar to VMS. Since Perl may have to
deal with file specifications in either VMS or Unix
syntax, it converts them to a single form when it must
operate on them directly. Either you've passed an
invalid file specification to Perl, or you've found a
case the conversion routines don't handle. Drat.
Execution of %s aborted due to compilation errors.
(F) The final summary message when a Perl compilation
fails.
Exiting eval via %s
(W) You are exiting an eval by unconventional means,
such as a a goto, or a loop control statement.
Exiting subroutine via %s
(W) You are exiting a subroutine by unconventional
means, such as a a goto, or a loop control statement.
Exiting substitution via %s
(W) You are exiting a substitution by unconventional
means, such as a a return, a goto, or a loop control
statement.
Fatal VMS error at %s, line %d
(P) An error peculiar to VMS. Something untoward
happened in a VMS system service or RTL routine;
Perl's exit status should provide more details. The
filename in "at %%%%ssss" and the line number in "line %%%%dddd"
tell you which section of the Perl source code is
distressed.
fcntl is not implemented
(F) Your machine apparently doesn't implement _f_c_n_t_l_(_).
What is this, a PDP-11 or something?
27/Feb/96 perl 5.002 with 16
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
Filehandle %s never opened
(W) An I/O operation was attempted on a filehandle
that was never initialized. You need to do an _o_p_e_n_(_)
or a _s_o_c_k_e_t_(_) call, or call a constructor from the
FileHandle package.
Filehandle %s opened only for input
(W) You tried to write on a read-only filehandle. If
you intended it to be a read-write filehandle, you
needed to open it with "+<" or "+>" or "+>>" instead
of with "<" or nothing. If you only intended to write
the file, use ">" or ">>". See the ooooppppeeeennnn entry in the
_p_e_r_l_f_u_n_c manpage.
Filehandle only opened for input
(W) You tried to write on a read-only filehandle. If
you intended it to be a read-write filehandle, you
needed to open it with "+<" or "+>" or "+>>" instead
of with "<" or nothing. If you only intended to write
the file, use ">" or ">>". See the ooooppppeeeennnn entry in the
_p_e_r_l_f_u_n_c manpage.
Final $ should be \$ or $name
(F) You must now decide whether the final $ in a
string was meant to be a literal dollar sign, or was
meant to introduce a variable name that happens to be
missing. So you have to put either the backslash or
the name.
Final @ should be \@ or @name
(F) You must now decide whether the final @ in a
string was meant to be a literal "at" sign, or was
meant to introduce a variable name that happens to be
missing. So you have to put either the backslash or
the name.
Format %s redefined
(W) You redefined a format. To suppress this warning,
say
{{{{
llllooooccccaaaallll $$$$^^^^WWWW ==== 0000;;;;
eeeevvvvaaaallll """"ffffoooorrrrmmmmaaaatttt NNNNAAAAMMMMEEEE ====............"""";;;;
}}}}
Format not terminated
(F) A format must be terminated by a line with a
solitary dot. Perl got to the end of your file
without finding such a line.
Found = in conditional, should be ==
(W) You said
27/Feb/96 perl 5.002 with 17
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
iiiiffff (((($$$$ffffoooooooo ==== 111122223333))))
when you meant
iiiiffff (((($$$$ffffoooooooo ======== 111122223333))))
(or something like that).
gdbm store returned %d, errno %d, key "%s"
(S) A warning from the GDBM_File extension that a
store failed.
gethostent not implemented
(F) Your C library apparently doesn't implement
_g_e_t_h_o_s_t_e_n_t_(_), probably because if it did, it'd feel
morally obligated to return every hostname on the
Internet.
get{sock,peer}name() on closed fd
(W) You tried to get a socket or peer socket name on a
closed socket. Did you forget to check the return
value of your _s_o_c_k_e_t_(_) call?
getpwnam returned invalid UIC %#o for user "%s"
(S) A warning peculiar to VMS. The call to ssssyyyyssss$$$$ggggeeeettttuuuuaaaaiiii
underlying the ggggeeeettttppppwwwwnnnnaaaammmm operator returned an invalid
UIC.
Glob not terminated
(F) The lexer saw a left angle bracket in a place
where it was expecting a term, so it's looking for the
corresponding right angle bracket, and not finding it.
Chances are you left some needed parentheses out
earlier in the line, and you really meant a "less
than".
Global symbol "%s" requires explicit package name
(F) You've said "use strict vars", which indicates
that all variables must either be lexically scoped
(using "my"), or explicitly qualified to say which
package the global variable is in (using "::").
goto must have label
(F) Unlike with "next" or "last", you're not allowed
to goto an unspecified destination. See the ggggoooottttoooo
entry in the _p_e_r_l_f_u_n_c manpage.
Had to create %s unexpectedly
(S) A routine asked for a symbol from a symbol table
that ought to have existed already, but for some
reason it didn't, and had to be created on an
emergency basis to prevent a core dump.
27/Feb/96 perl 5.002 with 18
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
Hash %%s missing the % in argument %d of %s()
(D) Really old Perl let you omit the % on hash names
in some spots. This is now heavily deprecated.
Identifier "%s::%s" used only once: possible typo
(W) Typographical errors often show up as unique
identifiers. If you had a good reason for having a
unique identifier, then just mention it again somehow
to suppress the message.
Illegal division by zero
(F) You tried to divide a number by 0. Either
something was wrong in your logic, or you need to put
a conditional in to guard against meaningless input.
Illegal modulus zero
(F) You tried to divide a number by 0 to get the
remainder. Most numbers don't take to this kindly.
Illegal octal digit
(F) You used an 8 or 9 in a octal number.
Illegal octal digit ignored
(W) You may have tried to use an 8 or 9 in a octal
number. Interpretation of the octal number stopped
before the 8 or 9.
Insecure dependency in %s
(F) You tried to do something that the tainting
mechanism didn't like. The tainting mechanism is
turned on when you're running setuid or setgid, or
when you specify ----TTTT to turn it on explicitly. The
tainting mechanism labels all data that's derived
directly or indirectly from the user, who is
considered to be unworthy of your trust. If any such
data is used in a "dangerous" operation, you get this
error. See the _p_e_r_l_s_e_c manpage for more information.
Insecure directory in %s
(F) You can't use _s_y_s_t_e_m_(_), _e_x_e_c_(_), or a piped open in
a setuid or setgid script if $$$$EEEENNNNVVVV{PATH} contains a
directory that is writable by the world. See the
_p_e_r_l_s_e_c manpage.
Insecure PATH
(F) You can't use _s_y_s_t_e_m_(_), _e_x_e_c_(_), or a piped open in
a setuid or setgid script if $$$$EEEENNNNVVVV{PATH} is derived
from data supplied (or potentially supplied) by the
user. The script must set the path to a known value,
using trustworthy data. See the _p_e_r_l_s_e_c manpage.
Internal inconsistency in tracking vforks
(S) A warning peculiar to VMS. Perl keeps track of
the number of times you've called ffffoooorrrrkkkk and eeeexxxxeeeecccc, in
27/Feb/96 perl 5.002 with 19
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
order to determine whether the current call to eeeexxxxeeeecccc
should be affect the current script or a subprocess
(see the eeeexxxxeeeecccc entry in the _p_e_r_l_v_m_s manpage). Somehow,
this count has become scrambled, so Perl is making a
guess and treating this eeeexxxxeeeecccc as a request to terminate
the Perl script and execute the specified command.
internal disaster in regexp
(P) Something went badly wrong in the regular
expression parser.
internal urp in regexp at /%s/
(P) Something went badly awry in the regular
expression parser.
invalid [] range in regexp
(F) The range specified in a character class had a
minimum character greater than the maximum character.
See the _p_e_r_l_r_e manpage.
ioctl is not implemented
(F) Your machine apparently doesn't implement _i_o_c_t_l_(_),
which is pretty strange for a machine that supports C.
junk on end of regexp
(P) The regular expression parser is confused.
Label not found for "last %s"
(F) You named a loop to break out of, but you're not
currently in a loop of that name, not even if you
count where you were called from. See the llllaaaasssstttt entry
in the _p_e_r_l_f_u_n_c manpage.
Label not found for "next %s"
(F) You named a loop to continue, but you're not
currently in a loop of that name, not even if you
count where you were called from. See the llllaaaasssstttt entry
in the _p_e_r_l_f_u_n_c manpage.
Label not found for "redo %s"
(F) You named a loop to restart, but you're not
currently in a loop of that name, not even if you
count where you were called from. See the llllaaaasssstttt entry
in the _p_e_r_l_f_u_n_c manpage.
listen() on closed fd
(W) You tried to do a listen on a closed socket. Did
you forget to check the return value of your _s_o_c_k_e_t_(_)
call? See the lllliiiisssstttteeeennnn entry in the _p_e_r_l_f_u_n_c manpage.
Literal @%s now requires backslash
(F) It used to be that Perl would try to guess whether
you wanted an array interpolated or a literal @. It
did this when the string was first used at runtime.
27/Feb/96 perl 5.002 with 20
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
Now strings are parsed at compile time, and ambiguous
instances of @ must be disambiguated, either by
putting a backslash to indicate a literal, or by
declaring (or using) the array within the program
before the string (lexically). (Someday it will
simply assume that an unbackslashed @ interpolates an
array.)
Method for operation %s not found in package %s during
blessing
(F) An attempt was made to specify an entry in an
overloading table that doesn't somehow point to a
valid method. See the _p_e_r_l_o_v_l manpage.
Might be a runaway multi-line %s string starting on line
%d
(S) An advisory indicating that the previous error may
have been caused by a missing delimiter on a string or
pattern, because it eventually ended earlier on the
current line.
Misplaced _ in number
(W) An underline in a decimal constant wasn't on a
3-digit boundary.
Missing $ on loop variable
(F) Apparently you've been programming in csh too
much. Variables are always mentioned with the $ in
Perl, unlike in the shells, where it can vary from one
line to the next.
Missing comma after first argument to %s function
(F) While certain functions allow you to specify a
filehandle or an "indirect object" before the argument
list, this ain't one of them.
Missing operator before %s?
(S) This is an educated guess made in conjunction with
the message "%s found where operator expected". Often
the missing operator is a comma.
Missing right bracket
(F) The lexer counted more opening curly brackets
(braces) than closing ones. As a general rule, you'll
find it's missing near the place you were last
editing.
Missing semicolon on previous line?
(S) This is an educated guess made in conjunction with
the message "%s found where operator expected". Don't
automatically put a semicolon on the previous line
just because you saw this message.
27/Feb/96 perl 5.002 with 21
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
Modification of a read-only value attempted
(F) You tried, directly or indirectly, to change the
value of a constant. You didn't, of course, try "2 =
1", since the compiler catches that. But an easy way
to do the same thing is:
ssssuuuubbbb mmmmoooodddd {{{{ $$$$____[[[[0000]]]] ==== 1111 }}}}
mmmmoooodddd((((2222))));;;;
Another way is to assign to a _s_u_b_s_t_r_(_) that's off the
end of the string.
Modification of non-creatable array value attempted,
subscript %d
(F) You tried to make an array value spring into
existence, and the subscript was probably negative,
even counting from end of the array backwards.
Modification of non-creatable hash value attempted,
subscript "%s"
(F) You tried to make a hash value spring into
existence, and it couldn't be created for some
peculiar reason.
Module name must be constant
(F) Only a bare module name is allowed as the first
argument to a "use".
msg%s not implemented
(F) You don't have System V message IPC on your
system.
Multidimensional syntax %s not supported
(W) Multidimensional arrays aren't written like
$$$$ffffoooooooo[1,2,3]. They're written like $$$$ffffoooooooo[1][2][3], as
in C.
Negative length
(F) You tried to do a read/write/send/recv operation
with a buffer length that is less than 0. This is
difficult to imagine.
nested *?+ in regexp
(F) You can't quantify a quantifier without
intervening parens. So things like ** or +* or ?* are
illegal.
Note, however, that the minimal matching quantifiers,
*?, +? and ?? appear to be nested quantifiers, but
aren't. See the _p_e_r_l_r_e manpage.
No #! line
(F) The setuid emulator requires that scripts have a
well-formed #! line even on machines that don't
27/Feb/96 perl 5.002 with 22
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
support the #! construct.
No %s allowed while running setuid
(F) Certain operations are deemed to be too insecure
for a setuid or setgid script to even be allowed to
attempt. Generally speaking there will be another way
to do what you want that is, if not secure, at least
securable. See the _p_e_r_l_s_e_c manpage.
No ----eeee allowed in setuid scripts
(F) A setuid script can't be specified by the user.
No comma allowed after %s
(F) A list operator that has a filehandle or "indirect
object" is not allowed to have a comma between that
and the following arguments. Otherwise it'd be just
another one of the arguments.
No command into which to pipe on command line
(F) An error peculiar to VMS. Perl handles its own
command line redirection, and found a '|' at the end
of the command line, so it doesn't know whither you
want to pipe the output from this command.
No DB::DB routine defined
(F) The currently executing code was compiled with the
----dddd switch, but for some reason the perl5db.pl file (or
some facsimile thereof) didn't define a routine to be
called at the beginning of each statement. Which is
odd, because the file should have been required
automatically, and should have blown up the require if
it didn't parse right.
No dbm on this machine
(P) This is counted as an internal error, because
every machine should supply dbm nowadays, since Perl
comes with SDBM. See the _S_D_B_M___F_i_l_e manpage.
No DBsub routine
(F) The currently executing code was compiled with the
----dddd switch, but for some reason the perl5db.pl file (or
some facsimile thereof) didn't define a DB::sub
routine to be called at the beginning of each ordinary
subroutine call.
No error file after 2> or 2>> on command line
(F) An error peculiar to VMS. Perl handles its own
command line redirection, and found a '2>' or a '2>>'
on the command line, but can't find the name of the
file to which to write data destined for stderr.
No input file after < on command line
(F) An error peculiar to VMS. Perl handles its own
command line redirection, and found a '<' on the
27/Feb/96 perl 5.002 with 23
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
command line, but can't find the name of the file from
which to read data for stdin.
No output file after > on command line
(F) An error peculiar to VMS. Perl handles its own
command line redirection, and found a lone '>' at the
end of the command line, so it doesn't know whither
you wanted to redirect stdout.
No output file after > or >> on command line
(F) An error peculiar to VMS. Perl handles its own
command line redirection, and found a '>' or a '>>' on
the command line, but can't find the name of the file
to which to write data destined for stdout.
No Perl script found in input
(F) You called ppppeeeerrrrllll ----xxxx, but no line was found in the
file beginning with #! and containing the word "perl".
No setregid available
(F) Configure didn't find anything resembling the
_s_e_t_r_e_g_i_d_(_) call for your system.
No setreuid available
(F) Configure didn't find anything resembling the
_s_e_t_r_e_u_i_d_(_) call for your system.
No space allowed after ----IIII
(F) The argument to ----IIII must follow the ----IIII immediately
with no intervening space.
No such pipe open
(P) An error peculiar to VMS. The internal routine
_m_y___p_c_l_o_s_e_(_) tried to close a pipe which hadn't been
opened. This should have been caught earlier as an
attempt to close an unopened filehandle.
No such signal: SIG%s
(W) You specified a signal name as a subscript to %%%%SSSSIIIIGGGG
that was not recognized. Say kkkkiiiillllllll ----llll in your shell to
see the valid signal names on your system.
Not a CODE reference
(F) Perl was trying to evaluate a reference to a code
value (that is, a subroutine), but found a reference
to something else instead. You can use the _r_e_f_(_)
function to find out what kind of ref it really was.
See also the _p_e_r_l_r_e_f manpage.
Not a format reference
(F) I'm not sure how you managed to generate a
reference to an anonymous format, but this indicates
you did, and that it didn't exist.
27/Feb/96 perl 5.002 with 24
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
Not a GLOB reference
(F) Perl was trying to evaluate a reference to a "type
glob" (that is, a symbol table entry that looks like
****ffffoooooooo), but found a reference to something else
instead. You can use the _r_e_f_(_) function to find out
what kind of ref it really was. See the _p_e_r_l_r_e_f
manpage.
Not a HASH reference
(F) Perl was trying to evaluate a reference to a hash
value, but found a reference to something else
instead. You can use the _r_e_f_(_) function to find out
what kind of ref it really was. See the _p_e_r_l_r_e_f
manpage.
Not a perl script
(F) The setuid emulator requires that scripts have a
well-formed #! line even on machines that don't
support the #! construct. The line must mention perl.
Not a SCALAR reference
(F) Perl was trying to evaluate a reference to a
scalar value, but found a reference to something else
instead. You can use the _r_e_f_(_) function to find out
what kind of ref it really was. See the _p_e_r_l_r_e_f
manpage.
Not a subroutine reference
(F) Perl was trying to evaluate a reference to a code
value (that is, a subroutine), but found a reference
to something else instead. You can use the _r_e_f_(_)
function to find out what kind of ref it really was.
See also the _p_e_r_l_r_e_f manpage.
Not a subroutine reference in %OVERLOAD
(F) An attempt was made to specify an entry in an
overloading table that doesn't somehow point to a
valid subroutine. See the _p_e_r_l_o_v_l manpage.
Not an ARRAY reference
(F) Perl was trying to evaluate a reference to an
array value, but found a reference to something else
instead. You can use the _r_e_f_(_) function to find out
what kind of ref it really was. See the _p_e_r_l_r_e_f
manpage.
Not enough arguments for %s
(F) The function requires more arguments than you
specified.
Not enough format arguments
(W) A format specified more picture fields than the
next line supplied. See the _p_e_r_l_f_o_r_m manpage.

PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
Null filename used
(F) You can't require the null filename, especially
since on many machines that means the current
directory! See the rrrreeeeqqqquuuuiiiirrrreeee entry in the _p_e_r_l_f_u_n_c
manpage.
NULL OP IN RUN
(P) Some internal routine called _r_u_n_(_) with a null
opcode pointer.
Null realloc
(P) An attempt was made to realloc NULL.
NULL regexp argument
(P) The internal pattern matching routines blew it
bigtime.
NULL regexp parameter
(P) The internal pattern matching routines are out of
their gourd.
Odd number of elements in hash list
(S) You specified an odd number of elements to a hash
list, which is odd, since hash lists come in key/value
pairs.
oops: oopsAV
(S) An internal warning that the grammar is screwed
up.
oops: oopsHV
(S) An internal warning that the grammar is screwed
up.
Operation `%s' %s: no method found,
(F) An attempt was made to use an entry in an
overloading table that somehow no longer points to a
valid method. See the _p_e_r_l_o_v_l manpage.
Operator or semicolon missing before %s
(S) You used a variable or subroutine call where the
parser was expecting an operator. The parser has
assumed you really meant to use an operator, but this
is highly likely to be incorrect. For example, if you
say "*foo *foo" it will be interpreted as if you said
"*foo * 'foo'".
Out of memory for yacc stack
(F) The yacc parser wanted to grow its stack so it
could continue parsing, but _r_e_a_l_l_o_c_(_) wouldn't give it
more memory, virtual or otherwise.
Out of memory!
(X) The _m_a_l_l_o_c_(_) function returned 0, indicating there
27/Feb/96 perl 5.002 with 26
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
was insufficient remaining memory (or virtual memory)
to satisfy the request.
page overflow
(W) A single call to _w_r_i_t_e_(_) produced more lines than
can fit on a page. See the _p_e_r_l_f_o_r_m manpage.
panic: ck_grep
(P) Failed an internal consistency check trying to
compile a grep.
panic: ck_split
(P) Failed an internal consistency check trying to
compile a split.
panic: corrupt saved stack index
(P) The savestack was requested to restore more
localized values than there are in the savestack.
panic: die %s
(P) We popped the context stack to an eval context,
and then discovered it wasn't an eval context.
panic: do_match
(P) The internal _p_p___m_a_t_c_h_(_) routine was called with
invalid operational data.
panic: do_split
(P) Something terrible went wrong in setting up for
the split.
panic: do_subst
(P) The internal _p_p___s_u_b_s_t_(_) routine was called with
invalid operational data.
panic: do_trans
(P) The internal _d_o___t_r_a_n_s_(_) routine was called with
invalid operational data.
panic: goto
(P) We popped the context stack to a context with the
specified label, and then discovered it wasn't a
context we know how to do a goto in.
panic: INTERPCASEMOD
(P) The lexer got into a bad state at a case modifier.
panic: INTERPCONCAT
(P) The lexer got into a bad state parsing a string
with brackets.
panic: last
(P) We popped the context stack to a block context,
and then discovered it wasn't a block context.

panic: leave_scope clearsv
(P) A writable lexical variable became readonly
somehow within the scope.
panic: leave_scope inconsistency
(P) The savestack probably got out of sync. At least,
there was an invalid enum on the top of it.
panic: malloc
(P) Something requested a negative number of bytes of
malloc.
panic: mapstart
(P) The compiler is screwed up with respect to the
_m_a_p_(_) function.
panic: null array
(P) One of the internal array routines was passed a
null AV pointer.
panic: pad_alloc
(P) The compiler got confused about which scratch pad
it was allocating and freeing temporaries and lexicals
from.
panic: pad_free curpad
(P) The compiler got confused about which scratch pad
it was allocating and freeing temporaries and lexicals
from.
panic: pad_free po
(P) An invalid scratch pad offset was detected
internally.
panic: pad_reset curpad
(P) The compiler got confused about which scratch pad
it was allocating and freeing temporaries and lexicals
from.
panic: pad_sv po
(P) An invalid scratch pad offset was detected
internally.

(P) The compiler got confused about which scratch pad
it was allocating and freeing temporaries and lexicals
from.

context frame.
panic: realloc
(P) Something requested a negative number of bytes of
realloc.
panic: restartop
(P) Some internal routine requested a goto (or
something like it), and didn't supply the destination.
panic: return
(P) We popped the context stack to a subroutine or
eval context, and then discovered it wasn't a
subroutine or eval context.
panic: scan_num
(P) _s_c_a_n___n_u_m_(_) got called on something that wasn't a
number.
panic: sv_insert
(P) The _s_v___i_n_s_e_r_t_(_) routine was told to remove more
string than there was string.
panic: top_env
(P) The compiler attempted to do a goto, or something
weird like that.
panic: yylex
(P) The lexer got into a bad state while processing a
case modifier.
Parens missing around "%s" list
(W) You said something like
mmmmyyyy $$$$ffffoooooooo,,,, $$$$bbbbaaaarrrr ==== @@@@____;;;;
when you meant
mmmmyyyy (((($$$$ffffoooooooo,,,, $$$$bbbbaaaarrrr)))) ==== @@@@____;;;;
Remember that "my" and "local" bind closer than comma.
Perl %3.3f required--this is only version %s, stopped
(F) The module in question uses features of a version
of Perl more recent than the currently running
version. How long has it been since you upgraded,
anyway? See the rrrreeeeqqqquuuuiiiirrrreeee entry in the _p_e_r_l_f_u_n_c
manpage.
Permission denied
(F) The setuid emulator in suidperl decided you were
up to no good.
27/Feb/96 perl 5.002 with 29
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
pid %d not a child
(W) A warning peculiar to VMS. _W_a_i_t_p_i_d_(_) was asked to
wait for a process which isn't a subprocess of the
current process. While this is fine from VMS'
perspective, it's probably not what you intended.
POSIX getpgrp can't take an argument
(F) Your C compiler uses POSIX _g_e_t_p_g_r_p_(_), which takes
no argument, unlike the BSD version, which takes a
pid.
Possible memory corruption: %s overflowed 3rd argument
(F) An _i_o_c_t_l_(_) or _f_c_n_t_l_(_) returned more than Perl was
bargaining for. Perl guesses a reasonable buffer
size, but puts a sentinel byte at the end of the
buffer just in case. This sentinel byte got
clobbered, and Perl assumes that memory is now
corrupted. See the iiiiooooccccttttllll entry in the _p_e_r_l_f_u_n_c
manpage.
Precedence problem: open %s should be open(%s)
(S) The old irregular construct
ooooppppeeeennnn FFFFOOOOOOOO |||||||| ddddiiiieeee;;;;
is now misinterpreted as
ooooppppeeeennnn((((FFFFOOOOOOOO |||||||| ddddiiiieeee))));;;;
because of the strict regularization of Perl 5's
grammar into unary and list operators. (The old open
was a little of both.) You must put parens around the
filehandle, or use the new "or" operator instead of
"||".
print on closed filehandle %s
(W) The filehandle you're printing on got itself
closed sometime before now. Check your logic flow.
printf on closed filehandle %s
(W) The filehandle you're writing to got itself closed
sometime before now. Check your logic flow.
Probable precedence problem on %s
(W) The compiler found a bare word where it expected a
conditional, which often indicates that an || or &&
was parsed as part of the last argument of the
previous construct, for example:
ooooppppeeeennnn FFFFOOOOOOOO |||||||| ddddiiiieeee;;;;
Prototype mismatch: (%s) vs (%s)
(S) The subroutine being defined had a predeclared
27/Feb/96 perl 5.002 with 30
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
(forward) declaration with a different function
prototype.
Read on closed filehandle <%s>
(W) The filehandle you're reading from got itself
closed sometime before now. Check your logic flow.
Reallocation too large: %lx
(F) You can't allocate more than 64K on an MSDOS
machine.
Recompile perl with ----DDDDDEBUGGING to use ----DDDD switch
(F) You can't use the ----DDDD option unless the code to
produce the desired output is compiled into Perl,
which entails some overhead, which is why it's
currently left out of your copy.
Recursive inheritance detected
(F) More than 100 levels of inheritance were used.
Probably indicates an unintended loop in your
inheritance hierarchy.
Reference miscount in sv_replace()
(W) The internal _s_v___r_e_p_l_a_c_e_(_) function was handed a
new SV with a reference count of other than 1.
regexp memory corruption
(P) The regular expression engine got confused by what
the regular expression compiler gave it.
regexp out of space
(P) A "can't happen" error, because _s_a_f_e_m_a_l_l_o_c_(_)
should have caught it earlier.
regexp too big
(F) The current implementation of regular expression
uses shorts as address offsets within a string.
Unfortunately this means that if the regular
expression compiles to longer than 32767, it'll blow
up. Usually when you want a regular expression this
big, there is a better way to do it with multiple
statements. See the _p_e_r_l_r_e manpage.
Reversed %s= operator
(W) You wrote your assignment operator backwards. The
= must always comes last, to avoid ambiguity with
subsequent unary operators.
Runaway format
(F) Your format contained the ~~ repeat-until-blank
sequence, but it produced 200 lines at once, and the
200th line looked exactly like the 199th line.
Apparently you didn't arrange for the arguments to
exhaust themselves, either by using ^ instead of @
27/Feb/96 perl 5.002 with 31
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
(for scalar variables), or by shifting or popping (for
array variables). See the _p_e_r_l_f_o_r_m manpage.
Scalar value @%s[%s] better written as $%s[%s]
(W) You've used an array slice (indicated by @) to
select a single value of an array. Generally it's
better to ask for a scalar value (indicated by $).
The difference is that $$$$ffffoooooooo[&bar] always behaves like
a scalar, both when assigning to it and when
evaluating its argument, while @@@@ffffoooooooo[&bar] behaves like
a list when you assign to it, and provides a list
context to its subscript, which can do weird things if
you're only expecting one subscript.
On the other hand, if you were actually hoping to
treat the array element as a list, you need to look
into how references work, since Perl will not
magically convert between scalars and lists for you.
See the _p_e_r_l_r_e_f manpage.
Script is not setuid/setgid in suidperl
(F) Oddly, the suidperl program was invoked on a
script with its setuid or setgid bit set. This
doesn't make much sense.
Search pattern not terminated
(F) The lexer couldn't find the final delimiter of a
// or m{} construct. Remember that bracketing
delimiters count nesting level.
seek() on unopened file
(W) You tried to use the _s_e_e_k_(_) function on a
filehandle that was either never opened or has been
closed since.
select not implemented
(F) This machine doesn't implement the _s_e_l_e_c_t_(_) system
call.
sem%s not implemented
(F) You don't have System V semaphore IPC on your
system.
semi-panic: attempt to dup freed string
(S) The internal _n_e_w_S_V_s_v_(_) routine was called to
duplicate a scalar that had previously been marked as
free.
Semicolon seems to be missing
(W) A nearby syntax error was probably caused by a
missing semicolon, or possibly some other missing
operator, such as a comma.
27/Feb/96 perl 5.002 with 32
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
Send on closed socket
(W) The filehandle you're sending to got itself closed
sometime before now. Check your logic flow.
Sequence (?#... not terminated
(F) A regular expression comment must be terminated by
a closing parenthesis. Embedded parens aren't
allowed. See the _p_e_r_l_r_e manpage.
Sequence (?%s...) not implemented
(F) A proposed regular expression extension has the
character reserved but has not yet been written. See
the _p_e_r_l_r_e manpage.
Sequence (?%s...) not recognized
(F) You used a regular expression extension that
doesn't make sense. See the _p_e_r_l_r_e manpage.
Server error
Also known as "500 Server error". This is a CGI
error, not a Perl error. You need to make sure your
script is executable, is accessible by the user CGI is
running the script under (which is probably not the
user account you tested it under), does not rely on
any environment variables (like PATH) from the user it
isn't running under, and isn't in a location where the
CGI server can't find it, basically, more or less.
setegid() not implemented
(F) You tried to assign to $), and your operating
system doesn't support the _s_e_t_e_g_i_d_(_) system call (or
equivalent), or at least Configure didn't think so.
seteuid() not implemented
(F) You tried to assign to $>, and your operating
system doesn't support the _s_e_t_e_u_i_d_(_) system call (or
equivalent), or at least Configure didn't think so.
setrgid() not implemented
(F) You tried to assign to $(, and your operating
system doesn't support the _s_e_t_r_g_i_d_(_) system call (or
equivalent), or at least Configure didn't think so.
setruid() not implemented
(F) You tried to assign to $<, and your operating
system doesn't support the _s_e_t_r_u_i_d_(_) system call (or
equivalent), or at least Configure didn't think so.
Setuid/gid script is writable by world
(F) The setuid emulator won't run a script that is
writable by the world, because the world might have
written on it already.
27/Feb/96 perl 5.002 with 33
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
shm%s not implemented
(F) You don't have System V shared memory IPC on your
system.
shutdown() on closed fd
(W) You tried to do a shutdown on a closed socket.
Seems a bit superfluous.
SIG%s handler "%s" not defined.
(W) The signal handler named in %%%%SSSSIIIIGGGG doesn't, in fact,
exist. Perhaps you put it into the wrong package?
sort is now a reserved word
(F) An ancient error message that almost nobody ever
runs into anymore. But before sort was a keyword,
people sometimes used it as a filehandle.
Sort subroutine didn't return a numeric value
(F) A sort comparison routine must return a number.
You probably blew it by not using <<<<====>>>> or ccccmmmmpppp, or by
not using them correctly. See the ssssoooorrrrtttt entry in the
_p_e_r_l_f_u_n_c manpage.
Sort subroutine didn't return single value
(F) A sort comparison subroutine may not return a list
value with more or less than one element. See the
ssssoooorrrrtttt entry in the _p_e_r_l_f_u_n_c manpage.
Split loop
(P) The split was looping infinitely. (Obviously, a
split shouldn't iterate more times than there are
characters of input, which is what happened.) See the
sssspppplllliiiitttt entry in the _p_e_r_l_f_u_n_c manpage.
Stat on unopened file <%s>
(W) You tried to use the _s_t_a_t_(_) function (or an
equivalent file test) on a filehandle that was either
never opened or has been closed since.
Statement unlikely to be reached
(W) You did an _e_x_e_c_(_) with some statement after it
other than a _d_i_e_(_). This is almost always an error,
because _e_x_e_c_(_) never returns unless there was a
failure. You probably wanted to use _s_y_s_t_e_m_(_) instead,
which does return. To suppress this warning, put the
_e_x_e_c_(_) in a block by itself.
Subroutine %s redefined
(W) You redefined a subroutine. To suppress this
warning, say

eeeevvvvaaaallll """"ssssuuuubbbb nnnnaaaammmmeeee {{{{ ............ }}}}"""";;;;
}}}}
Substitution loop
(P) The substitution was looping infinitely.
(Obviously, a substitution shouldn't iterate more
times than there are characters of input, which is
what happened.) See the discussion of substitution in
the section on _Q_u_o_t_e _a_n_d _Q_u_o_t_e_l_i_k_e _O_p_e_r_a_t_o_r_s in the
_p_e_r_l_o_p manpage.
Substitution pattern not terminated
(F) The lexer couldn't find the interior delimiter of
a s/// or s{}{} construct. Remember that bracketing
delimiters count nesting level.
Substitution replacement not terminated
(F) The lexer couldn't find the final delimiter of a
s/// or s{}{} construct. Remember that bracketing
delimiters count nesting level.
substr outside of string
(W) You tried to reference a _s_u_b_s_t_r_(_) that pointed
outside of a string. That is, the absolute value of
the offset was larger than the length of the string.
See the ssssuuuubbbbssssttttrrrr entry in the _p_e_r_l_f_u_n_c manpage.
suidperl is no longer needed since...
(F) Your Perl was compiled with
----DDDDSETUID_SCRIPTS_ARE_SECURE_NOW, but a version of the
setuid emulator somehow got run anyway.
syntax error
(F) Probably means you had a syntax error. Common
reasons include:
AAAA kkkkeeeeyyyywwwwoooorrrrdddd iiiissss mmmmiiiissssssssppppeeeelllllllleeeedddd....
AAAA sssseeeemmmmiiiiccccoooolllloooonnnn iiiissss mmmmiiiissssssssiiiinnnngggg....

AAAA cccclllloooossssiiiinnnngggg qqqquuuuooootttteeee iiiissss mmmmiiiissssssssiiiinnnngggg....
Often there will be another error message associated
with the syntax error giving more information.
(Sometimes it helps to turn on ----wwww.) The error message
itself often tells you where it was in the line when
it decided to give up. Sometimes the actual error is
several tokens before this, since Perl is good at
understanding random input. Occasionally the line
number may be misleading, and once in a blue moon the
27/Feb/96 perl 5.002 with 35
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
only way to figure out what's triggering the error is
to call ppppeeeerrrrllll ----cccc repeatedly, chopping away half the
program each time to see if the error went away. Sort
of the cybernetic version of 20 questions.
syntax error at line %d: `%s' unexpected
(A) You've accidentally run your script through the
Bourne shell instead of Perl. Check the <#!> line, or
manually feed your script into Perl yourself.
System V IPC is not implemented on this machine
(F) You tried to do something with a function
beginning with "sem", "shm" or "msg". See the sssseeeemmmmccccttttllll
entry in the _p_e_r_l_f_u_n_c manpage, for example.
Syswrite on closed filehandle
(W) The filehandle you're writing to got itself closed
sometime before now. Check your logic flow.
tell() on unopened file
(W) You tried to use the _t_e_l_l_(_) function on a
filehandle that was either never opened or has been
closed since.
Test on unopened file <%s>
(W) You tried to invoke a file test operator on a
filehandle that isn't open. Check your logic. See
also the section on _-_X in the _p_e_r_l_f_u_n_c manpage.
That use of $[ is unsupported
(F) Assignment to $[ is now strictly circumscribed,
and interpreted as a compiler directive. You may only
say one of
$$$$[[[[ ==== 0000;;;;
$$$$[[[[ ==== 1111;;;;
............
llllooooccccaaaallll $$$$[[[[ ==== 0000;;;;
llllooooccccaaaallll $$$$[[[[ ==== 1111;;;;
............
This is to prevent the problem of one module changing
the array base out from under another module
inadvertently. See the section on _$_[ in the _p_e_r_l_v_a_r
manpage.
The %s function is unimplemented
The function indicated isn't implemented on this
architecture, according to the probings of Configure.
The crypt() function is unimplemented due to excessive
paranoia.
(F) Configure couldn't find the _c_r_y_p_t_(_) function on
your machine, probably because your vendor didn't
27/Feb/96 perl 5.002 with 36
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
supply it, probably because they think the U.S.
Govermnment thinks it's a secret, or at least that
they will continue to pretend that it is. And if you
quote me on that, I will deny it.
The stat preceding ----llll ____ wasn't an lstat
(F) It makes no sense to test the current stat buffer
for symbolic linkhood if the last stat that wrote to
the stat buffer already went past the symlink to get
to the real file. Use an actual filename instead.
times not implemented
(F) Your version of the C library apparently doesn't
do _t_i_m_e_s_(_). I suspect you're not running on Unix.
Too few args to syscall
(F) There has to be at least one argument to _s_y_s_c_a_l_l_(_)
to specify the system call to call, silly dilly.
Too many ('s
Too many )'s
(A) You've accidentally run your script through ccccsssshhhh
instead of Perl. Check the <#!> line, or manually
feed your script into Perl yourself.
Too many args to syscall
(F) Perl only supports a maximum of 14 args to
_s_y_s_c_a_l_l_(_).
Too many arguments for %s
(F) The function requires fewer arguments than you
specified.
trailing \ in regexp
(F) The regular expression ends with an unbackslashed
backslash. Backslash it. See the _p_e_r_l_r_e manpage.
Translation pattern not terminated
(F) The lexer couldn't find the interior delimiter of
a tr/// or tr[][] construct.
Translation replacement not terminated
(F) The lexer couldn't find the final delimiter of a
tr/// or tr[][] construct.
truncate not implemented
(F) Your machine doesn't implement a file truncation
mechanism that Configure knows about.
Type of arg %d to %s must be %s (not %s)
(F) This function requires the argument in that
position to be of a certain type. Arrays must be
@@@@NNNNAAAAMMMMEEEE or @{EXPR}. Hashes must be %%%%NNNNAAAAMMMMEEEE or %{EXPR}.
27/Feb/96 perl 5.002 with 37
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
No implicit dereferencing is allowed--use the {EXPR}
forms as an explicit dereference. See the _p_e_r_l_r_e_f
manpage.
umask: argument is missing initial 0
(W) A umask of 222 is incorrect. It should be 0222,
since octal literals always start with 0 in Perl, as
in C.
Unable to create sub named "%s"
(F) You attempted to create or access a subroutine
with an illegal name.
Unbalanced context: %d more PUSHes than POPs
(W) The exit code detected an internal inconsistency
in how many execution contexts were entered and left.
Unbalanced saves: %d more saves than restores
(W) The exit code detected an internal inconsistency
in how many values were temporarily localized.
Unbalanced scopes: %d more ENTERs than LEAVEs
(W) The exit code detected an internal inconsistency
in how many blocks were entered and left.
Unbalanced tmps: %d more allocs than frees
(W) The exit code detected an internal inconsistency
in how many mortal scalars were allocated and freed.
Undefined format "%s" called
(F) The format indicated doesn't seem to exist.
Perhaps it's really in another package? See the
_p_e_r_l_f_o_r_m manpage.
Undefined sort subroutine "%s" called
(F) The sort comparison routine specified doesn't seem
to exist. Perhaps it's in a different package? See
the ssssoooorrrrtttt entry in the _p_e_r_l_f_u_n_c manpage.
Undefined subroutine &%s called
(F) The subroutine indicated hasn't been defined, or
if it was, it has since been undefined.
Undefined subroutine called
(F) The anonymous subroutine you're trying to call
hasn't been defined, or if it was, it has since been
undefined.
Undefined subroutine in sort
(F) The sort comparison routine specified is declared
but doesn't seem to have been defined yet. See the

_p_e_r_l_f_o_r_m manpage.
unexec of %s into %s failed!
(F) The _u_n_e_x_e_c_(_) routine failed for some reason. See
your local FSF representative, who probably put it
there in the first place.
Unknown BYTEORDER
(F) There are no byteswapping functions for a machine
with this byte order.
unmatched () in regexp
(F) Unbackslashed parentheses must always be balanced
in regular expressions. If you're a vi user, the %
key is valuable for finding the matching paren. See
the _p_e_r_l_r_e manpage.
Unmatched right bracket
(F) The lexer counted more closing curly brackets
(braces) than opening ones, so you're probably missing
an opening bracket. As a general rule, you'll find
the missing one (so to speak) near the place you were
last editing.
unmatched [] in regexp
(F) The brackets around a character class must match.
If you wish to include a closing bracket in a
character class, backslash it or put it first. See
the _p_e_r_l_r_e manpage.
Unquoted string "%s" may clash with future reserved word
(W) You used a bare word that might someday be claimed
as a reserved word. It's best to put such a word in
quotes, or capitalize it somehow, or insert an
underbar into it. You might also declare it as a
subroutine.
Unrecognized character \%03o ignored
(S) A garbage character was found in the input, and
ignored, in case it's a weird control character on an
EBCDIC machine, or some such.
Unrecognized signal name "%s"
(F) You specified a signal name to the _k_i_l_l_(_) function
that was not recognized. Say kkkkiiiillllllll ----llll in your shell to
see the valid signal names on your system.
Unrecognized switch: -%s
(F) You specified an illegal option to Perl. Don't do
that. (If you think you didn't do that, check the #!
line to see if it's supplying the bad switch on your
27/Feb/96 perl 5.002 with 39
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
behalf.)
Unsuccessful %s on filename containing newline
(W) A file operation was attempted on a filename, and
that operation failed, PROBABLY because the filename
contained a newline, PROBABLY because you forgot to
_c_h_o_p_(_) or _c_h_o_m_p_(_) it off. See the cccchhhhoooopppp entry in the
_p_e_r_l_f_u_n_c manpage.
Unsupported directory function "%s" called
(F) Your machine doesn't support _o_p_e_n_d_i_r_(_) and
_r_e_a_d_d_i_r_(_).
Unsupported function %s
(F) This machines doesn't implement the indicated
function, apparently. At least, Configure doesn't
think so.
Unsupported socket function "%s" called
(F) Your machine doesn't support the Berkeley socket
mechanism, or at least that's what Configure thought.
Unterminated <> operator
(F) The lexer saw a left angle bracket in a place
where it was expecting a term, so it's looking for the
corresponding right angle bracket, and not finding it.
Chances are you left some needed parentheses out
earlier in the line, and you really meant a "less
than".
Use of $# is deprecated
(D) This was an ill-advised attempt to emulate a
poorly defined awk feature. Use an explicit _p_r_i_n_t_f_(_)
or _s_p_r_i_n_t_f_(_) instead.
Use of $* is deprecated
(D) This variable magically turned on multiline
pattern matching, both for you and for any luckless
subroutine that you happen to call. You should use
the new ////////mmmm and ////////ssss modifiers now to do that without
the dangerous action-at-a-distance effects of $$$$****.
Use of %s in printf format not supported
(F) You attempted to use a feature of printf that is
accessible only from C. This usually means there's a
better way to do it in Perl.
Use of %s is deprecated
(D) The construct indicated is no longer recommended
for use, generally because there's a better way to do
it, and also because the old way has bad side effects.
Use of bare << to mean <<"" is deprecated
(D) You are now encouraged to use the explicitly
27/Feb/96 perl 5.002 with 40
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
quoted form if you wish to use a blank line as the
terminator of the here-document.
Use of implicit split to @_ is deprecated
(D) It makes a lot of work for the compiler when you
clobber a subroutine's argument list, so it's better
if you assign the results of a _s_p_l_i_t_(_) explicitly to
an array (or list).
Use of uninitialized value
(W) An undefined value was used as if it were already
defined. It was interpreted as a "" or a 0, but maybe
it was a mistake. To suppress this warning assign an
initial value to your variables.
Useless use of %s in void context
(W) You did something without a side effect in a
context that does nothing with the return value, such
as a statement that doesn't return a value from a
block, or the left side of a scalar comma operator.
Very often this points not to stupidity on your part,
but a failure of Perl to parse your program the way
you thought it would. For example, you'd get this if
you mixed up your C precedence with Python precedence
and said
$$$$oooonnnneeee,,,, $$$$ttttwwwwoooo ==== 1111,,,, 2222;;;;
when you meant to say
(((($$$$oooonnnneeee,,,, $$$$ttttwwwwoooo)))) ==== ((((1111,,,, 2222))));;;;
Another common error is to use ordinary parentheses to
construct a list reference when you should be using
square or curly brackets, for example, if you say
$$$$aaaarrrrrrrraaaayyyy ==== ((((1111,,,,2222))));;;;
when you should have said
$$$$aaaarrrrrrrraaaayyyy ==== [[[[1111,,,,2222]]]];;;;
The square brackets explicitly turn a list value into
a scalar value, while parentheses do not. So when a
parenthesized list is evaluated in a scalar context,
the comma is treated like C's comma operator, which
throws away the left argument, which is not what you
want. See the _p_e_r_l_r_e_f manpage for more on this.
Variable "%s" is not exported
(F) While "use strict" in effect, you referred to a
global variable that you apparently thought was
imported from another module, because something else
of the same name (usually a subroutine) is exported by
27/Feb/96 perl 5.002 with 41
PERLDIAG(1) User Contributed Perl Documentation PERLDIAG(1)
that module. It usually means you put the wrong funny
character on the front of your variable.
Variable syntax.
(A) You've accidentally run your script through ccccsssshhhh
instead of Perl. Check the <#!> line, or manually
feed your script into Perl yourself.
Warning: unable to close filehandle %s properly.
(S) The implicit _c_l_o_s_e_(_) done by an _o_p_e_n_(_) got an
error indication on the close(0. This usually
indicates your filesystem ran out of disk space.
Warning: Use of "%s" without parens is ambiguous
(S) You wrote a unary operator followed by something
that looks like a binary operator that could also have
been interpreted as a term or unary operator. For
instance, if you know that the rand function has a
default argument of 1.0, and you write
rrrraaaannnndddd ++++ 5555;;;;
you may THINK you wrote the same thing as
rrrraaaannnndddd(((()))) ++++ 5555;;;;
but in actual fact, you got
rrrraaaannnndddd((((++++5555))));;;;
So put in parens to say what you really mean.
Write on closed filehandle
(W) The filehandle you're writing to got itself closed
sometime before now. Check your logic flow.
X outside of string
(F) You had a pack template that specified a relative
position before the beginning of the string being
unpacked. See the ppppaaaacccckkkk entry in the _p_e_r_l_f_u_n_c manpage.
x outside of string
(F) You had a pack template that specified a relative
position after the end of the string being unpacked.
See the ppppaaaacccckkkk entry in the _p_e_r_l_f_u_n_c manpage.
Xsub "%s" called in sort
(F) The use of an external subroutine as a sort
comparison is not yet supported.

You can't use ----llll on a filehandle
(F) A filehandle represents an opened file, and when
you opened the file it already went past any symlink
you are presumably trying to look for. Use a filename
instead.
YOU HAVEN'T DISABLED SET-ID SCRIPTS IN THE KERNEL YET!
(F) And you probably never will, since you probably
don't have the sources to your kernel, and your vendor
probably doesn't give a rip about what you want. Your
best bet is to use the wrapsuid script in the eg
directory to put a setuid C wrapper around your
script.
You need to quote "%s"
(W) You assigned a bareword as a signal handler name.
Unfortunately, you already have a subroutine of that
name declared, which means that Perl 5 will try to
call the subroutine when the assignment is executed,
which is probably not what you want. (If it IS what
you want, put an & in front.)
[gs]etsockopt() on closed fd
(W) You tried to get or set a socket option on a
closed socket. Did you forget to check the return
value of your _s_o_c_k_e_t_(_) call? See the ggggeeeettttssssoooocccckkkkoooopppptttt entry
in the _p_e_r_l_f_u_n_c manpage.
\1 better written as $1
(W) Outside of patterns, backreferences live on as
variables. The use of backslashes is grandfathered on
the righthand side of a substitution, but
stylistically it's better to use the variable form
because other Perl programmers will expect it, and it
works better if there are more than 9 backreferences.
'|' and '<' may not both be specified on command line
(F) An error peculiar to VMS. Perl does its own
command line redirection, and found that STDIN was a
pipe, and that you also tried to redirect STDIN using
'|' and '>' may not both be specified on command line
(F) An error peculiar to VMS. Perl does its own
command line redirection, and thinks you tried to
redirect stdout both to a file and into a pipe to
another command. You need to choose one or the other,
though nothing's stopping you from piping into a
program or Perl script which 'splits' output into two
streams, such as
