Nope, not quite ready. When I tried to add a large file to an
archive, I got this error message:

The message is clearly bogus - the file is 4GB+ of nothing but
binary zeros so the compression is surpassingly good! I think the
problem is that the code doesn't expect a file > 4GB to be fitting into
an archive < 4 GB.
I've got to track down why this happens. The strange thing is that
it didn't happen with the regular Unix build, just the cmsmvs build.
Oh, well. We keep plodding along.

Do you have some batch JCL for zip set up?
