I am trying to set a decent size project for my students, who use 
Arity Prolog on IBM-PCs. The trouble is that even the most modest Prolog
program runs out of stack space more or less immediately. (For example,
a Turing machine simulator that I got them to write only runs for a hundred
or so steps before running out of space).

Does anyone have any suggestions that might help? (this might be a DOS 
problem rather than a Prolog program, just knowing that fact might help a
bit). Will a different Prolog (eg Prolog2) be better?

Cheers

Are you familiar with how to make Prolog programs tail-recursive?
Any recursive algorithm will run out of stack space if it recurses
enough times, unless certain conditions are met.  See O'Keefe's
_The Craft of Prolog_ or my _Prolog Programming in Depth_.
