README file for "macshrd"
Author: Keldon Jones (keldon@ont.com)


This is a version of Terry Winograd's "SHRDLU" program with some minor
modifications so that it will work with my simple "maclisp" interpreter.
To run it, start the maclisp interpreter and enter:

(load 'newload)

It should load all the required files and then present the "READY"
prompt.  Type in a sentence for the system to parse and respond to.

**IMPORTANT** Put a space between the last word in the sentence and the
punctuation mark.

Here's some sample sentences to try.  Not all of them work (those are
marked with a '*').

pick up a big red block . (*)
grasp the pyramid .
what does the box contain ?
what is the pyramid supported by ?
how many blocks are not in the box ?


The original Winograd sources are in the "attic" directory.  There have
been as few changes as possible made to them.  Some were necessary
however, especially in "smspec" where some bizarre bitrot seems to have
happened.  Other changes were made to make up for inadequacies in the
MacLISP interpreter I wrote.
