Zoo
A Fast File Archiver
Version 1.10 - 24 August 1986
by
Rahul Dhesi
INTRODUCTION
Zoo is a utility for creating and maintaining libraries or archives of files
in compressed form. It requires a computer system with MS-DOS version 2.00
or greater. IBM compatibility is not a requirement.
Zoo is a 29 kilobyte executable file. It can extract archived files in
about 80 kilobytes of available memory, and can function fully in about 110
kilobytes of available memory.
A companion program, Ooz, is also provided. All that Ooz can do is extract
files from Zoo archives, but it occupies less disk space (about 11 kilo-
bytes) and needs less available memory (about 60 kilobytes).
Also provided is AtoZ, a batch program that will convert a subdirectory full
of files in other formats (especially *.LBR or *.ARC) to Zoo archives.
Versions 1.x of Zoo, Ooz and AtoZ are in the public domain. This means that
you can freely use them, make copies, give them away, and even sell them.
The source code is not being distributed, but version 2.00 of Zoo, when it
appears, will be accompanied by generic source code in C.
DISCLAIMER
Zoo, Ooz, and Atoz are provided to you on an "as is", "you owe me nothing, I
owe you nothing" basis. If this warranty gives you any specific legal
rights, I would like to know what they are, especially if they vary from
state to state.
COMMAND SUMMARY
Zoo has two types of commands: Expert commands, which consist of one com-
mand letter followed by zero or more modifier characters, and Novice com-
mands, which consist of a hyphen ("-") followed by a command word that may
be abbreviated. Novice commands let you begin using Zoo quickly. Unlike
Expert commands, which are case-sensitive, Novice commands can be given in
any combination of upper- and lowercase characters.
Expert commands are cryptic but offer you many more flexible options. Start
with the Novice commands and switch to using the Expert commands as soon as
you can.
1. Zoo Novice Command Format:
ZOO cmd archive[.ZOO] [file] ...
The "archive" is the filename of the archive you want to use, and the
program will assume an extension of ".ZOO" if you do not supply one. The
"file" is any filespec.
Both the "archive" and the "file" names may be pathnames. Pathnames may
contain both "/" and "\" characters. The "file" name (but not the "archive"
name) may also contain the standard DOS-style wildcard characters "*" and
"?". The "..." means that several filespecs may be given, separated by
spaces.
A filespec ending with "/" or "\" is assumed to refer to all files in that
directory.
Each Novice command works in two stages. First, the command does its inten-
ded work. Then, if the result was that one or more files were deleted in
the specified archive, the archive is packed to recover space.
If packing occurs, an unpacked backup copy of the archive is always left
behind, with an extension of ".bak". The packed archive always appears in
the current directory, even if the original archive was on a different disk.
This is intended to allow you to economize on disk space by simply using two
disks if there is not enough space on a single disk to hold both the archive
and its backup copy.

Novice commands may be abbreviated as much as you wish, up to a minimum of a
hyphen ("-") followed by at least one command character. For example, the
novice command "-extract" may be abbreviated to "-ext", "-ex", or "-e".
Novice commands are described in more detail later.
2. Zoo Expert Command Format:
ZOO {acDehlPTuUvx}[dEfnMNoOpPquv1] archive[.ZOO] [file] ...
The characters enclosed within {} are commands. Choose any one of these.
The characters enclosed within [] just to the right of the {} are modifiers
and zero or more of these may immediately follow the command character. All
combinations of command and modifier characters may not be valid.
In general, [] encloses something that may (sometimes) be omitted and {}
encloses a set of items from which exactly one must be selected. The
archive and file names are as described for Novice commands above. The
archive and file names may be in any combination of upper- and lowercase
characters, but the command and modifier characters are case-sensitive.
Invoking Zoo as "zoo h" will give a help screen. Zoo Expert commands are
described in detail later.
3. Ooz Command Format
The Ooz command format is as follows:
OOZ archive[.ZOO] [file] ...
Ooz is trivial to use; just give it the name of the archive and it will
extract all files from it, or specify which files you want to extract and
only those will be extracted. All extracted files go into the current
directory.
NOVICE COMMANDS
1. Adding Files to an Archive
Format: ZOO -add archive[.ZOO] file ...
The specified files are added to the archive. If all specified files
were added without any error, and if this resulted in deletion of a
file that was already in the archive, the archive is packed. If
packing of the archive occurs, the unpacked archive is renamed to have
an extension of ".bak" and the packed archive always appears in the
current directory on the current disk.
For example, the command "zoo -add qmodem *.com *.00? \doc\q*.doc"
would add the following files to archive "qmodem.zoo": all files of
the form *.com and *.00? in the current directory, and all files of the
form q*.doc in the \doc subdirectory.
The archive can be in a different directory or on a different disk.
Thus "zoo -add c:\scandals\misc \fortran\ \cobol\*.doc" adds files to
the archive "misc.zoo" in the directory "c:\scandals". The files added
are: all files in the directory "\fortran" and all *.doc files in the
directory "\cobol".
If the filespecs given match duplicate filenames, each matching
filename is used only once. This is true even if the duplicate
filenames refer to different files in different directories.
Zoo will not add an archive to itself, nor add the archive's backup to
itself, nor add the temporary file {zoo}.@@@ to an archive, nor add any
other file that has the same name as these.
3. Moving Files to an Archive
Format: ZOO -move archive[.ZOO] file ...
-Move works just like -add, except that after all files have been
added, if no error occurred, the added files are deleted from disk.
4. Testing an Archive
Format: ZOO -test archive[.ZOO]
This is equivalent to the -extract command, except that extracted files
are not saved. If no CRC error or other error occurs during execution
of the -test command, this indicates with a high degree of confidence
that the archive is not corrupted.
5. Printing Files from an Archive
Format: ZOO -print archive[.ZOO] [file] ...
This option extracts specified files from the archive and sends the
extracted data to standard output, which is normally the screen. The
output may be directed to a printer or a disk file using DOS's redirec-
tion character ">".
Zoo precedes the data of each extracted file by a brief header
displaying the name of the file.
Error messages are piped to standard output as well. However, if a bad
CRC is detected, the bad CRC message is sent both to the screen and to
the standard output.
6. Deleting Files in an Archive
Format: ZOO -delete archive[.ZOO] file ...
The specified files are deleted from the archive, and then the archive
is packed to recover space that was occupied by the deleted files.
As a safety feature, if the user deletes all files in an archive, no
packing of the archive is done and the deleted files may be recovered
with the Expert command U (undelete). To delete an archive entirely,
use DOS's "del" or "erase" command.
7. Listing Files in an Archive
Format: ZOO -list archive[.ZOO] [file] ...
This gives a list of the specified files along with information about
each file's original size, size as stored in the archive, compression
factor, and date. If no files are specified, all files in the archive
are listed.
If a file would need to be extracted with a version of Zoo higher than
the current version, Zoo displays the minimum version number needed.
A summary line displays a count of files listed, the total of all
original sizes and current sizes, and a net compression factor. The
actual size of an archive is always somewhat greater than the total of
the current sizes of files in it because of the directory information
that is also kept in the archive.
8. Updating an Archive
Format: ZOO -update archive[.ZOO] file ...
This command is like -add, except that if a file being added is already
in the archive, it is added only if the copy being added is newer than
the copy already in the archive. The -update commands adds all the
files that the -freshen command would add (below) and also adds any
files that are not already in the archive.
9. Freshening an Archive
Format: ZOO -freshen archive[.ZOO] file ...
This command is like -add, except that a file is added only if it is
already in the archive, AND if the copy being added is newer than the
copy already in the archive.
The -freshen command simply brings archived files up to date without
adding any files that weren't already in the archive.
10. Adding comments to an Archive
Format: ZOO -comment archive[.ZOO] file ...
Zoo allows each archived file to have an optional attached comment.
Any comment attached to a file is listed when the Novice -list command
is given. The -comment command allows comments to be attached,
removed, and updated.
When invoked with the -comment command, Zoo goes through the specified
archive and for each matching file, shows you the comment (if any) and
allows you to type a replacement comment. Your choices are:
o Type a carriage return alone to leave unchanged any attached
comment.
o Type "/END" and carriage return to remove any comment attached to
the file.
o Type a comment of up to 65,535 characters long. Terminate it by
typing "/END" by itself on the last line. The new comment will
replace any previous comment.
For better formatting in listings, keep each line of the comment to 77
characters or less. Since comments are not compressed, they should not
be excessively long.
It is possible to create a file of comments with a text editor and give
it to Zoo as input using DOS's input redirection character "<". In
this case, the comments in the file must be in exact sequence. If this
input file has fewer comments than Zoo expects, comments for remaining
matching files will be left unchanged.
If end-of-file is reached before all comments have been accounted for,
Zoo simply leaves all remaining files' comments unchanged. End-of-file
can be caused by the user typing a control Z interactively or the
redirected input being smaller than Zoo expects.
Examples: "zoo -comment batch *.bat" shows any comment that may be
attached to each *.bat file in the archive "batch.zoo", allows you to
type a new comment. Type as many lines as you wish, then type "/END"
by itself on a line to terminate the comment. If, however, you want to
leave the original comment unchanged, just hit return. You may type
control Z at any point to leave all remaining files' comments
unchanged.
"zoo -comment qmodem *.doc *.00? <qcomment.txt" makes Zoo read new
comments from the file "qcomment.txt". For each file matching *.doc
and *.00?, Zoo reads data from qcomment.txt and reacts exactly as with
interactive input: an empty line (carriage return alone) in
"qcomment.txt" leaves the original comment unchanged; "/END" by itself
removes the original comment; any other text terminated by "/END" on a
separate line replaces a comment. If "qcomment.txt" ends prematurely,
all remaining files have their comments left unchanged.
EXPERT COMMANDS
1. Adding Files to an Archive
Format: ZOO {au}[cfMnPqu] archive[.ZOO] file ...
Command characters:
a Add files to archive. If "a" is used by itself, each file is
added either in compressed or in uncompressed form, whichever is
smaller. To add files without compressing them, use the "f"
(fast) modifier. If a file with the same name as one being added
is already present in the archive, it is marked as deleted. For
more information about deleted files, see the D (delete), U
(undelete), and P (pack) commands.
If the filespecs given match duplicate filenames, each matching
filename is used only once. This is true even if the duplicate
filenames refer to different files in different directories.
Zoo will not add an archive to itself, nor add the archive's
backup to itself, nor add the temporary file {zoo}.@@@ to an
archive, nor add any other file that has the same name as these.
u Update archive. A specified file is added to the archive if
a copy of it is already in the archive and the copy being added is
newer than the copy already in the archive.
Modifiers:
c Add comments when adding files. After each file is added, the
user is prompted for a comment. If the file being added has
replaced a file already in the archive, any comment attached to
the replaced file is shown to the user and becomes attached to the
newly-added file unless the user changes it. Responses are exac-
tly as for the Novice -comment command and the Expert c command:
hit carriage return to leave any previous comment unchanged; type
"/END" to leave the file without any comment; or type a comment
and terminate with "/END" on a line by itself.
If the user types control Z in response to a request for a com-
ment, Zoo will no longer ask for comments for any subsequent files
and their previous comments, if any, will remain unchanged.
Note: Since comments for replaced files become automatically
attached to corresponding newly-added files, the freshening of an
archive with the Novice -freshen command or the Expert au command
does not cause loss of comments.
f Do a fast add/update by not compressing files as they are added.
M Move files to archive. This makes Zoo erase the original files
after they have been added to the archive. Files are erased after
addition of files to the archive is complete, and after any
requested packing of the archive has been done, and only if Zoo
detected no errors.
n Add new files only. A specified file is added only if it isn't
already in the archive.
P Pack archive after files have been added. Normally, when Zoo adds
a file to an archive and if there was already a copy of the file
in the archive, the old copy is marked as being deleted. This
does not actually remove the old copy; it exists in the archive
and may be undeleted or extracted. Packing the archive permanen-
tly removes all deleted files from it and recovers the space they
were using.
The original archive is never changed during the packing process
except that it is renamed to have an extension of ".bak". The
packed archive always appears in the current directory on the
current disk.
q Be quiet. Normally Zoo lists the name of each file as it is
added. The q modifier suppresses this. Any error messages are
always shown.
u Update archive. This has exactly the same effect as when used as
a command character (see above).
All combinations of the [cfMnPqu] modifiers are valid. The combination of n
and u together adds a file to the archive either if the file is not already
in the archive, OR if the file is already in the archive but the archived
copy is older than the copy being added.
Examples:
"zoo a pascal *.*" adds all files in the current directory to the ar-
chive called "pascal.zoo". If the archive does not already exist,
it is created. Each file is added in compressed or uncompressed
form, whichever is smaller.
"zoo aM pascal *.*" adds the same files and then deletes the original
unarchived files.
"zoo af pascal *.*" adds the same files without any compression.
"zoo aP pascal *.pas" adds all files matching "*.pas" to the archive
"pascal.zoo". After all specified files have been added, Zoo packs
the archive if it finds any deleted files in it.
"zoo aPc pascal *.pas" does exactly the same but also prompt the user
for a comment for each file after it is added.
"zoo nfP a:/archives/cobol /cobol/" adds all files in the the /cobol
subdirectory on the current disk to the archive "cobol.zoo" in the
subdirectory "a:/archives", without doing compression. After the
files have been added, if Zoo finds any deleted files in the
archive, it packs the archive. Packing leaves the original
archive unchanged but renamed to have an extension of ".bak". A
new packed copy of it appears in the current directory of the
current disk.
"zoo uq silence silence.com / c:\bin\*.exe" adds the following
files to archive "silence.zoo": (a) the file "silence.com";
(b) all files in the root directory; (c) all files in the direc-
tory c:\bin that have the extension ".exe". However, since the
command u was used, no file is added unless a copy of it is
already present in the archive. Because of the q modifier, Zoo
does not list names of files as they are added.
Extracting Files from an Archive
Novice: zoo -extract archive [file] ...
Expert: zoo {ex}[dNoOpq] archive [file] ...
The e and x commands are synonymous. The specified files are
extracted from the archive. If no file was
specified, all files are extracted from the archive. All extracted
files go into the current directory.
The following modifiers are specific to the e and x commands:
N Do not save extracted data but report any errors encountred. The
integrity of deleted files will not be checked unless the d modifier
is used.
O Overwrite files. Normally, if a file being extracted would over-
write an already-existing file of the same name, Zoo asks you if
you really want to overwrite it. You may answer the question with
"y", which means yes, overwrite; or "n", which means no, don't
overwrite; or "a", which means assume the answer is "y" for this
and all subsequent files.
The O modifier makes Zoo assume that files may always be
overwritten. It may not be combined with the N or p modifiers.
o The o modifier is equivalent to the O modifier if and only if it
is given at least twice. It is otherwise ignored.
p Pipe extracted data to standard output.
Error messages are piped to standard output as well. However, if a
bad CRC is detected, the bad CRC message is sent both to standard
error and and to the standard output.
2. Listing Files in an Archive
Format: ZOO {lv}[dfv] archive[.ZOO] [file] ...
Command characters:
l List filenames in archive. A list of all filenames in the archive
is presented, including the date and time of each file, its origi-
nal size, its current size as stored in the archive, and the per-
centage size decrease due to compression (called CF or compression
factor). If no filespec is supplied, all files in the archive are
shown except deleted files. Optionally, deleted files may be
listed; see the description of the d modifier.
If a file would need to be extracted with a version of Zoo higher
than the current version, Zoo displays the minimum version number
needed.
A summary line displays a count of files listed, the total of all
original sizes and current sizes, and a net compression factor.
The actual size of an archive is always somewhat greater than the
total of the current sizes of files in it because of the directory
information that is also kept in the archive.
v Verbose list. Equivalent to l but also shows any comment attached
to each file. Version 2.00 of Zoo is expected to allow the user
to specify that only the first n lines of each comment be shown.
Modifiers:
d List deleted files also. Normally, only files that have not been
deleted are shown. The d modifier gives a combined display inclu-
ding both deleted and not deleted files. Deleted files are marked
in the normal listing with "DEL". Giving the the d modifier at
least twice (e.g., "zoo ldd archive") displays only deleted files.
f Fast listing. The listing gives a multicolumn display of only the
filenames, followed by a count of deleted files. Overrrides the v
command and the v modifier and prevents any comments from being
listed.
v Verbose list. Equivalent to the v command.
The d modifiers may be separately combined with the f and v modifiers. If
the f and v modifiers are used together, f overrrides v.
3. Deleting Files in an Archive
Format: ZOO D[Pq1] archive[.ZOO] file ...
Command character:
D Delete files. The specified files are marked as being deleted.
The file remains in the archive, however, and may be listed and
extracted. The file does not permanently disappear until the
archive is packed (see the P modifier below and the P command
elsewhere). If there are multiple instances of the file in the
archive, all are deleted; the 1 modifier will prevent this.
Modifiers:
P Pack archive. After the delete command has taken effect, and if
at least one file was deleted, Zoo proceeds to pack the archive.
Packing the archive permanently removes all deleted files from the
archive. The packed archive always appears in the current
disk/directory and the original unpacked archive is renamed to
have an extension of ".bak". (To not keep the backup copy, use
the P command described elsewhere.) See also the P modifier to
the a command.
As a safety feature, if the user deletes all files in an archive,
no packing is done and the deleted files may be recovered with the
U command. To delete an archive entirely, use DOS's "del" or
"erase" command.
q Be quiet. As files are deleted, their names are normally listed
on the screen. The q modifier suppresses this information. Error
messages are always shown.
1 One file only. This option (the digit one, not the letter ell)
makes Zoo delete at most one file, regardless of how many file-
names match the supplied filespecs. This option allows the user
to selectively delete only the first of multiple occurrences of
the same file. See also the 1 modifier to the U (undelete)
command.
4. Undeleting Files in an Archive
Format: ZOO U[q1] archive[.ZOO] file ...
Command character:
U Undelete files. The specified files are marked as being no longer
deleted. If there are multiple instances of the same deleted
file, all are undeleted; the 1 modifier will prevent this.
Modifiers:
q Be quiet. As files are undeleted, their names normally are listed
on the screen. The q modifier suppresses this information. Error
messages are always shown.
1 One file only. This option (the digit one, not the letter ell)
makes Zoo undelete at most one file. Regardless of how many files
match the filespec(s) supplied, Zoo stops after undeleting one.
Every time a file is added to an archive, any (one) previous
archived file having the same name is marked deleted. If the same
file is repeatedly added to an archive, multiple deleted instances
of the file appear in the archive. Any one of these may be
selectively extracted by careful and patient successive use of the
1 option combined with the U (undelete) and D (delete) commands.
5. Adjusting the Timestamp of an Archive
Format: ZOO T[q] archive[.ZOO]
Command character:
T Zoo normally tries to always keep time and date stamp of archives
to be the same as that of the newest file in the archive. The T
command allows this to be done manually at any time. An
informative message is given.
The T command is useful if you have downloaded an archive via
telecommunications and you want to fix its timestamp to reflect
the age of the newest file in the archive.
Modifier:
q The q modifier suppresses the informative message.
6. Packing an Archive
Format: ZOO P[EPq] archive[.ZOO]
Command character:
P When Zoo adds a file to an archive, any previous instance of that
file in the archive is marked as deleted but remains in the ar-
chive. The P command packs an archive and permanently removes all
deleted files from it. Unless the user specifies otherwise, the
original archive is renamed to have the extension ".bak" and
remains otherwise unchanged. The packed archive always appears on
the current disk/directory.
Files appearing in the packed archive will retain any attached
comments.
Floppy disk users who pack an archive that takes up more than half
the disk space should keep the original archive on a disk differ-
ent from the current disk. The packed copy of the archive will
appear on the current disk.
Zoo archives can pick up garbage at the end because of Xmodem file
transfers or due to being stored on certain computer systems that
round up file size to a power of two. The P command will truncate
such an archive to its proper size.
If packing an archive would result in nothing being left in the
archive, the packing leaves the archive unchanged.
Modifiers:
E When an archive is packed, the original copy of the archive is
normally not deleted but simply renamed to have the extension
".bak". For example, packing "apple.zoo" will give a new packed
archive called "apple.zoo", and a backup copy "apple.bak" that is
identical to the original archive. The user may specify deletion
of the backup copy with the E modifier.
P Normally, if Zoo finds that a backup copy of an archive already
exists, it will refuse to pack the archive again, for that would
mean losing the old backup copy. The P forces Zoo to proceed with
packing and delete the old backup copy. For example, suppose both
"london.zoo" and "london.bak" exist. Zoo will give an error
message in response to the command "zoo P london"; however, it
will pack the archive if the command "zoo PP london" is given.
When packing is done, the packed archive is initially created as a temporary
file called "{zoo}.@@@". After successful packing, this temporary file is
renamed to the name of the original archive while the original archive is
renamed to have an extension of ".bak". If archive packing is aborted for
any reason, the temporary file "{zoo}.@@@" is left in the directory. This
file also appears if, after packing is completed, Zoo is unable to rename
this file to the name of the original archive.
DISK SPACE CONSIDERATIONS
When Zoo is adding files to an archive, it gives an error message and exits
as soon as disk space is too low to add the next specified file.
When Zoo is extracting files from an archive, however, it attempts to go on
as long as it can. If a file being extracted would exceed the space avail-
able on disk, Zoo gives an error message but goes on to attempt to extract
the next matching file. It aborts entirely only if the disk becomes
completely full.
Archive packing requires enough disk space to create a new copy of the
archive. The archive to be packed may be kept on a disk other than the
current disk. The packed archive appears on the current disk.
INTERRUPTING WITH CONTROL C
Zoo may be interrupted with control C at any time.
Aborting operation with control C should not result in any damaged files.
Rapid repeated hitting of control C could potentially leave files in an
inconsistent state, although it has not been observed to happen. (If you
hit control C once and Zoo doesn't seem to notice, it probably missed it;
it should be safe to wait about five seconds and try again.)
Because of the way MS-DOS handles user interrupts, it was found necessary,
to preserve archive integrity, that Zoo disable break status (shown and set
by the DOS "break" command). Zoo 1.03N does not restore break status to its
original value when it exits; version 2.00 is expected to do so.
EXIT STATUS
Zoo returns an exit status of 0 if no errors occurred, and 1 if an error
occurred or if no files matched when listing an archive. This exit status
may be tested in a batch file using the DOS "if errorlevel 1 goto ..."
statement or from an executing parent process using DOS system call 4D
hexadecimal.
ARCHIVE INTEGRITY
When Zoo adds a file to an archive, it is always appended to the end of the
archive, so a system crash should not normally affect the integrity of the
archive. If Zoo is interrupted while adding a file to an archive, the added
file may not show up as being in the archive but some or all of its data
will have been appended to the archive. The P (pack) command will restore
the archive to its original size.
When Zoo appends a file to an archive and a previous instance of the same
file exists in the archive, the previous instance is marked deleted. This
involves a direct (random) access write to the archive. In theory, if there
were a system crash while the disk hardware was writing an updated directory
entry in an archive, damage to the archive could occur. In practice, this
is likely to be very rare.
It is recommended that backup copies be always kept of valuable archives.
CONVERSION FROM OTHER FORMATS TO ZOO FORMAT
The batch program ATOZ.BAT can help you convert a subdirectory full of files
in another format (such as *.LBR and *.ARC) to Zoo format. See ATOZ.DOC for
instructions. Due to differences between the batch languages of DOS 3.x and
DOS 2.x, Atoz 1.00 works only with DOS 2.x.
VERSION COMPATIBILITY
Zoo 1.10 can add information to an archive in the form of attached comments
that earlier versions of Zoo cannot interpret. Earlier versions of Zoo will
list and extract files from version 1.10 archives and delete and undelete
files in them. But to avoid any loss of information, earlier versions of
Zoo will refuse to modify version 1.10 archives in any other way. Instead,
the following message will be given: "Version 1.10 of Zoo is needed to
fully manipulate this archive."
VERSION 2.00
Version 2.00, when released, is expected to have the following additional
features:
1. Filename listings will be alphabetized.
2. Source code in (fairly) generic *NIX-compatible C will be available.
3. A listing of files in the archive will show the first N lines of the
comment for each file, N being specified by the user.
4. Multiple instances of the same file in an archive will be properly
handled, each being identified by a version number.
5. It will be possible to execute archived programs. Zoo will directly
extract the program into memory and execute it rather than creating a
temporary file first.
