Current DOS products from both Arity and Quintus allow only 64k (1 segment) of
stack space for each of the stacks--so, yes, they do run out almost instantly
if you're passing around large terms.

Arity's "solution" is their OS/2 product--which is utterly useless to those of
us who know better than to move to OS/2.

Quintus (actually LPA) has announced a 386 version of their DOS implementation,
which will thus have no specific memory limits (it runs under a DOS extender,
so can access all the memory in the computer).  This, to my way of thinking, is
the way to go.  (Ken, is this product available yet?)
