You might want to look at the VMS documentation or online help for the
system service $FORCEX. I can't comment on whether it will help in
JF's particular case, but it clearly exists, does pretty much what you
describe (forces the exit of an image in another process, without
terminating the process), and is even potentially relevant on VMS
versions prior to V7.3 (a long way prior, in fact).

At least one example of $FORCEX documentation can be found (for now)
in the System Services Reference at

http://h71000.www7.hp.com/doc/73final/4527/4527pro_041.html

and there will doubtless be similar ones elsewhere for different
versions of VMS.

There's also discussion of $FORCEX in the relevant sections of the VMS
Programming Concepts manual, e.g. the section on Performing Image
Exit. There's one currently at:

http://h71000.www7.hp.com/doc/82final/5841/5841pro_016.html

There were some example $FORCEX programs in the ITRC, but although the
index entries are still Googlecached, the recent HP improvements to
the ITRC mean the content is lost (at least for those I tried).

Have a lot of fun,
