LARK VERSION 2.1
LARK VERSION 2.1M

LARK is a utility that is intended to be used in conjunction with the
popular PKXARC.COM program by PKWARE, Inc., and Mr. Vernon D. Buerg's
LIST.COM program. LARK "Front-Ends" these programs to provide a
user-friendly method of viewing the contents of files within an
archive without the bother of de-arcing the file first.
LARK eliminates the need of remembering sometimes vague or ambiguous
'option' codes, and mostly, it eliminates typing (and re-typing)
lengthy command lines.
To use LARK,
1. PKXARC.COM and LIST.COM must be named as such.
NOTE! Use version 3.5 of PKXARC only! (The next version of
LARK will support a wider variety of de-archivers.)
2. A path must exist to PKXARC.COM and LIST.COM.
3. Type in the command;
LARK filename[.ARC]
where 'filename' is the name of any archive file ending with
the extension of ".ARC".
LARK will then display a list of the files within the archive.
4. Use the up/down arrow keys to tab the cursor to the file you
want to inspect. (The Pg Up and Pg Dn keys will scroll the
list up/down and the HOME and END keys will jump to the top
or bottom of the list.)
5. Select one of the following options;
Press <V> to View the selected the file.
Press <X> to eXtract the selected file from the archive.
Press <E> to Extract all files from the archive.
Press <P> to Print the selected file.
Press <ESC> to exit to DOS.
Press <H> to display a list of these commands.
LARK was written using version 2.1 of Microsofts QuickBasic compiler,
along with a little help from Mr. Thomas Hanlin's ADVBAS routines and
a couple of custom assembly routines.
If enough interest is shown (i.e., users register their copies),
future versions of LARK will be released with additional bells and
whistles. Plans for the future include the addition of automatically
displaying a list of all *.ARC files on the current drive and the
ability to tailor LARK to your particular requirements via a built-
in configuration utility. Version 3.0 will be re-written in C. This
should solve most of the problems with systems using earlier versions
of DOS.
If you find this utility useful, a contribution of $15.00 would be
greatly appreciated. Please send all contributions to:

Thanks for using LARK!
LARK release notes
------------------
Version 1.0, Initial release, 4 JUN 87.
Version 1.1, released 5 JUN 87 -

to DOS.
Version 2.0, released 7 JUN 87 -

to LARK after viewing a file.
- Added PgUp/PgDn scrolling.
- HOME key goes to top of list, END key goes to bottom of list.
- Added command key functions for:
VIEW (V)
EXTRACT (E,X)
PRINT (P)
ON LINE HELP (F1)
Version 2.1, Released 12 JUN 87
- Restored the use of the RETURN Key to View files.
- Modified the 'beep' tone to a more pleasing(?) DTMF tone.
- The 'beep' no longer sounds when the HOME or END keys are pressed.
- Added additional command key,
ON LINE HELP (H)
- Released LARK021M.EXE. (Monochrome)
This version was designed to be used with systems that can't
handle the direct-to-screen displays and other advanced features
used in LARK021. It is a little slower scrolling, but is
otherwise identical to LARK021.EXE.
TECH NOTES:
About Piping... When LARK tells PKXARC.COM to extract a file
for viewing, the selected file is actually sent to the disk
(the root directory), and given an 8 digit filename. LIST.COM
then displays the file to the screen. When LIST is exited, the
file is deleted. If for any reason, you don't exit LIST in an
orderly fashion the file will be left in the root directory
of your disk. Additionally, if you are using LARK on a floppy
disk that is write-protected, you will get the DOS error message,
"Disk Write Protected, Abort, Retry, Ignore", when you try to
View a file.
PKWARE saw fit to change the structure of their option para-
meters from the '/' (in version 3.4) to the '-' (version 3.5).
Version 2.1 of LARK was designed to work with PKXARC version 3.5
only. Future versions of LARK will support a wider variety of
de-archivers, but for now, this will have to do.
