Yes, it will. The problem is that my current patch is very badly
borken [sic]. :-(.

This version of MVS unzip just sings "...and I don't like anybody
very much!" no matter what you feed it. I've tried it against a bunch
of zip files, old and new, always with the same result as Vikesh gets.
So far I've tracked it down to the fact that unzip isn't finding the
file size correctly - everything goes downhill from there. Somewhere
there is still an incompatible mix of 32-bit and 64-bit functions that
I haven't located yet.

Would a version of bzip2 help you out for the time being? I had just
done a z/OS USS port of the latest version (1.0.5) earlier this week,
before you reported the unzip problem. It supports large files, and
appears to be working well. I think it might work for you in
conjunction with Kirk's utilities.
The old version of bzip2 that used to be available from IBM has been
withdrawn; I don't know what version it was or whether it supported
large files. There is now a "supported" version which you have to pay
for, and looks to be heavily modified by IBM - mainly to provide
IBM-style messages, as far as I can tell. I can't imaginw wanting such
a beast, but that's the subject of a different thread!
I suggest this because I've no idea when I'll be able to fix the
unzip patch.
By the way, if you haven't done so, would you please post your
problem to the Info-ZIP form as well?
Cheers,
Bob
