Re: origin of "handle"

Thanks for your reply.  As you say, perhaps the term "handle" in
memory management was borrowed from the OS field.  But even if this is
so, I would like to know where the concept originated in the memory
management domain.  I'll take a look at Smalltalk's blue book but I'm
almost sure (as you suggest) that some older Lisp system must have
used this first.
