For that matter, at least one of us seems to
have a memory problem:

If you got that C compiler installed and
working, then you would probably be happier
if you built UnZip from a source kit. (And
if you read the documentation which comes
with it.)

If you did _not_ get the C compiler to work,
then one of the newer official VMS
object+executable kits may still include
enough good stuff to let you re-LINK, even on
an older VMS version than the one used to
make the kit. Again, the VMS-specific
documentation should explain how to do this.

As usual, many things are possible.

The OpenVMS FAQ goes into details on how to get and how to use zip and unzip. URLs include:

Yes, the 2006 edition is current. The VMS stuff hasn't changed all that much. I have a few updates posted at the first web site site. Download the text-format or (if you're on a system with a decent PDF viewer) PDF-format version as those are more easily searchable than the other formats. There is a full (zipped) download of all FAQ formats available, too.

Hunter Goatley's kits for zip and unzip were both current and were also built to run on VAX/VMS versions from around V5.5 or so and newer, AFAIK. These kits are here:

The HP kits for zip and unzip have usually been down-revision software versions of the tools, versions known to have bugs, and also clearly built for newer VMS versions.

This stuff all shows up in Google, as this topic was a frequent source of questions in past years.

And yes, there had been requests that VMS add zip and unzip into the base kit over the years.
