Not to be too picky, but GZIP should work on any file. The
problem that I saw in your log files yesterday I think had more to do with
trying to copy a variable record length file to tape as if it were fixed
record length. GZIP actually gets very good compression (at least under
UNIX) on zebra files. I admit I am not an "expert," but the worse that I
think could happen in this case is GZIP may strip the VMS info from the
file and you would have to add it again by modifying the VMS file
attributes.

I'll have to read earlier email to understand again how TAR and
GZIP are being used. But I thought in general the order is as Nicola
says, first TAR then GZIP. TAR (gnu version) has built in options for
both compressing and uncompressing archives done this way.
I realize that I am "out of the loop," so feel free to ignore my
comments if they really don't apply.
