[comp.lang.lisp] source req for "lisp macros for backtracking"

db@delphi.ACA.MCC.COM (David Murray Bridgeland) (10/19/89)

Hi!

In March 1989 _AI Expert_, Maxwell and Riggle presented 
some CL macros for backtracking.  They claimed the
source for those (500 lines)  are on the AI Expert BBS 
and on Compuserve.  Could someone who has the source
post it or email it to me?

My plans for Saturday night?
I thought I'd just hang out at the Gas 'n Sip.
