Almost everything here is ZIP'ed using Info-ZIP, a free program compatible with PKZIP. Info-ZIP Info-ZIP is available for many platforms, including OS/2, unix, MVS Open Edition, and now a non-OE MVS version. There is also a commercial unzip program for MVS available from ASI. I found where Info-Zip moved to and the link above has been corrected. (October 17, 2001)

After retrieving the file to your local PC or unix system, unzip it with the unzip program of your choice. Then upload (typically via ftp) the resulting file to your MVS system, setting LRECL=80 and RECFM=FB . If the file ends with the qualifier .netdata, or .zip you must transfer the file in BINARY. (If you're running some imitation OS from the 1980s, the final qualifier is likely to be .net instead of .netdata. Don't complain to me about that.)

If the file is a netdata file, after uploading it to MVS in binary (remember the FB80!) restore it via the following TSO command:
