Thanks Steven, What is happening is that files on Zos are being zipped and shipped to a Solaris platform as a data feed. Zos PKZIP has an option to generate a gzip format compressed file. So we have done that for many years - worked fine till recently.
It appears that when Zos PKZIP encounters a file > 4 GB changes format to ZIP64 - (should have abended instead of doing that without letting folk know). Solaris gzip has been failing). I'll try the info-ziplink you have suggested. Thanks for you help.

Why are you using gzip to handle archives created by PKZIP? I thought that PKZIP worked with ZIP archives, and that gzip's ZIP-archive capabilities were quite limited. There are programs which were designed to deal with ZIP archives, and they have been used on z/OS: http://www.info-zip.org/ I'm not a z/OS user, so I know nothing, but there is at least one in the Info-ZIP group, so you may be able to get some help if you have problems building or using the Info-ZIP Zip and UnZip programs on z/OS. > Also need to have SOLARIS support ensure their 'GZIP' understands the > ZIP64 file format. It's not my program, so I know nothing, but I would not bet that gzip on any system type can do this. The Info-ZIP programs definitely _can_ handle large-file ZIP archives on Solaris (although a version number would be an interesting datum when describing any OS). HP-UX, Tru64, and VMS, too, for that matter. ------------------------------------------------------------------------ Steven M.
