I've done major changes to the source code of ZZAP starting with version
5.9a. Most of these changes you should not notice. The changes were
mainly breaking the program up into more logical modules (units) and
cleaning up some sloppy code. However, with major changes to source code
often there are undesirable and unforseen side-effects (I won't say the
"B" word). I would appreciate hearing from anyone who experiences a
problem, a postcard describing the problem would be welcome. Describing
how to reproduce the problem would would most helpful.
CAUTION! The action of some of the command line switches have been
changed as well as their default settings.
Features added to version 6.2A:
- Can accept a filename containing an list of files to convert. The
file name must be preceded by an '@' character. The file
must be a standard ASCII text file with one file
specification per line.
- The log file name must be specified in the environment and
the /L switch is no longer accepted. This was necessary to
allow ZZAP to log errors before the configuration file is
processed.
Features added to version 6.1A:
- ZZAP will now allow subdirecty information to be included in
archives with the /B command line switch. The ARC= and
UNARC= configuration file commands must, however, be
properly configured to allow subdirecties.
- Temporary files are handled differently to make it possible
for ZZAP to work with multi-line BBS's without problems.
Previously, a conflict could have arisen if ZZAP was
creating the new archive and someone tried to access it
(e.g. view or download) it at the same time. The BBS must,
however, lock an archive to allow reading only while a
download is in program to avoid any possibility of a
conflict.
Features added to version 6.0A:
- Test-Only mode added so that a virus scan can be run as well as
a test of the archive integrity without the overhead of rebuilding
the archive.
- Three programs can be declared that will be executed just before
an archive is extracted, after the file have been extracted, and
after the new archive is created.
- The %COMSPEC% variable can be used when declaring programs to be
executed so that DOS (usually COMMAND.COM) can be executed to
run a batch file (or do whatever you desire).
- External programs can be defined to be executed just before and
just after an archive has been processed.
- More extensive control of time/date stamping of files has been
added. You can now set a file to today's date, keep the original
date, or set the date to that of the newest file contained in
the archive.
- Processing can optionally be skipped on files that are more than
a specified number of days old.
- Redirection of input is now supported so that you can automatically
add comments to some types of archives.
- You can now repack an archive to the same type, e.g. ZIP to ZIP,
to take advantage of improved compression techniques as well as
to test archive integrity and run a virus scan.
- Default command line options can be specified in the configuration
file.
- The target archive extension can be specified on the command line.
