Unzipping a VMS Archive
Restores the files and all their attributes as stored in the archive.
Can’t restore what wasn’t saved!
Notes:
To Unzip an archive on OpenVMS, simply invoke the Unzip program and specify the archive_name (.ZIP is assumed - the extension can be left off).
Note that Unzip can only restore the information present in the archive. There are no defaults for those characteristics that were not archived. If /VMS was not used to create the archive, some files may be unusable. /VERSION can be used if /KEEP_VERSION was used to create the archive. If version numbers were not saved in the archive, /VERSION has no effect.
