We use something called PSL (Portable Standard Lisp) from Univ. of Utah.
It has both a compiler and interpreter and *opinion* seems to be a heck
of a lot faster and far more efficient than DEC COMMON LISP.  We have
a version we created from Utah's Vax UNIX version; I think Utah will
have a VMS version of their own very soon.

PSL has a COMMON LISP compatability package, an object oriented
programming facility, and loads of other handy stuff.  Unlike COMMON
LISP PSL has a fixed sized heap with a two state garbage
collector.  A properly tuned PSL can be very fast (better
than C in many cases) and five or six can be
run at one time (while still doing other things).  Three DEC COMMON
LISPs can bog down a VMS 780 system.
