Hi Art,

Oh well! I thought maybe this would work. Has anybody tried any
experimenting along this line, and found anything useful? I periodically
have to move enough data that the 2G file size limit for an uncompressed
psuedo floppy is very incovenient.

Not sure about AIX but D3 Linux compressed pseudo-floppies ("p" in
/usr/lib/pick/pick0) writes files that can be uncompressed with gunzip.
Depending upon your distro you might have to rename the files to have a
".gz" extension:
$ mv filesave filesave.gz
$ gunzip filesave.gz

As I remember D3 for Linux links "compress" to "gzip" and "uncompress"
to "gunzip" during installation. This may not be the case on AIX. You
might want to try both gunzip and uncompress from the command line.

HTH,

My Bad! (Ooops!) I was pointing to the *compressed* file instead of the
*uncompressed* file. (blush) With ark you can specify either unix
compressed or gzip (or many other compression standards). It seems both
unix compressed and gzip work. Now I need to generate a full account-save
instead of the sample file I tested, and see what happens with multiple
cascaded files. BTW, my tape definition line in pick0 (aix) is:

tape /aixbak/filesave 10000000 p lx # tape 14 1000000 p lx
