Prolog turtle graphics.
lang/prolog/code/io/turtle/
This is a simple turtle graphics program for vt100 terminals written
by David Lau-Kee and originally posted to the Prolog Digest. A few
syntactic errors were corrected by Salleh Mustaffa, University of
Manchester. There may be some problems due to control characters in
the program not being properly transmitted through email in the
original posting.
A limited subset of turtle graphics capabilities is implemented: You
can tell the turtle to turn 90 degrees clockwise or anticlockwise, and
to move forward X steps. Backtracking over these primitives causes
them to be undone.
