[comp.sys.cbm] zip-unzip probs

XWUU@PURCCVM.BITNET (03/28/91)

I have yet to get a file up and running using the zip-unzip program!
The program will not accept the name of the file when it is listed in
the encryptd form: 1!filename, 2!filename, etc.  The only way I have
been able to get the program to run is to provide the filename '*' at
the prompt for the filename to unzip.  The program then runs and starts
to unzip the file(s), but then stops and hangs after 100 to 150 blocks of
writing.  I have no docs, any ideas?

Zip-Code is a shareware program by A. L. Peters, but I have not seen it
available for downloading anywhere.  Part of the problem is that
Zip-Code is encoded on the disk in such a way that you need to have
Zip-Code in order to send or receive the program.  Rather
self-defeating, wouldn't you say?  But be aware that the Zip/Unzip
program that you see around is only a small subest of the full Zip-Code,
which includes full documentation.

Now then, how to use Zip-Code...the program requires two disks at all
times, one for reading, one for writing.  When zipping a disk, the
entire disk is read, sector by sector, packed, and written to four
files, with 1!, 2!, 3!, 4! added to the filename.  When unzipping, these
four PRG files must be present on the source disk (or, if they are
large, they can be put on more than one disk).  The destination disk
WILL be formatted, so it must be blank, or have unneeded data.

When you want to unzip, you must type the name of the set of files,
without the numbers.  So if you have files called "1!FURBALLS", etc.,
then when asked for the source filename, type "FURBALLS", and the
program will figure out the rest.

One noted problem with Zip-Code is that it can have problems when the
zipped files have been padded out, say, via Xmodem.  There are ways to
remove Xmodem padding, in fact, some terminal programs have this
ability.

Need more info?  I might have it somewhere...
