I have just posted a LISP interpreter for MS-DOS called PC-LISP. It runs a subset of Franz lisp. It consists of three files: lisp.doc - A manual extfunc.l - A set of function definitions and a demo. pc-lisp.uuu - The uuencoded binary. A 112K .exe file. This interpreter is the result of 1 and a half years of work, it has full garbage collection and heap management. It allows lambda, nlambda and macro bodies, will run prog's, has types float, alpha, list and port. It incorporates shallow binding techniques for O(1) symbol lookup. It has access to the MS-DOS BIOS graphics routines. The demo is a small Turtle Graphics routine. It has full error detection including stack overflow. It has one break level from which you can analyze bindings at the point of error, show the stack up to the point of error, or trace a functions execution. It requires 256K but runs best with 512 or a full 640K. The three parts have been posted to net.sources Enjoy Peter Ashwood-Smith University of Toronto.
