As other Lisp implementations, VAX LISP/VMS could save its state:

2.11 USING SUSPENDED SYSTEMS
A suspended system is a binary file that is a copy of the LISP memory
in use during an interactive LISP session up to the point at which you
create the suspended system. The purpose of a suspended system is to
save the state of an interactive LISP session. You might want to do
this if your work is incomplete. By resuming LISP from a suspended
system, you can continue your work from the point at which you
stopped.

and a

1.1.6 Call-Out Facility
QvAX LISP includes a call-out facility, which lets you call programs
written in other VAX/VMS programming languages and programs that
include run-time library (RTL) routines and VMS and RMS system
services. Chapter 2 of the VAX LISP/VMS System Access Programming
Guide describes the call-out process and explains how to use the
call-out facility
