Thanks. Just don’t recall Lisp. I used SOAP on the IBM 650. Used my hands to plug 407 boards, sorter and punch/copier. Those were the days. Still have a handful of punch cards within reach.

Actually I think I do recall Lisp but never came in contact in my 44 years of progamming.

LISP was big in the AI community when true AI was “only 20 years away”. It’s all much harder than we thought.
