Making a VMS .ZIP Archive
$ ZIP/LEVEL=9/VMS archive_name filespec
Include /KEEP_VERSION to preserve VMS version numbers.
required when “filespec” includes a wild-carded version number (ex: *.*;*)
Notes:
Zip for OpenVMS does not store version numbers in the archive by default. If files must be restored with their original version numbers, use the /KEEP_VERSION qualifier.
Note that the /KEEP_VERSION qualifier is required when the “filespec” parameter includes a wild-carded version number. Otherwise, filename.ext’s within the archive would duplicate. The storage of the version number makes the filespec.’s unique, just as is seen in VMS.
