VMS is not (hawk, spit, gag) C, and (hawk, spit, gag) C is not VMS

There are a system services for using the DLM.  Callable from ALL VMS languages. 
  Even (hawk, spit, gag) C.

I don't know anything about LISP, and I don't know if a process image is 
re-startable.  Seems to me there might be a bit more to it.
