Dissecting thisForth - CH Ting
"I am trying to fully understand Wil Baden's thisForth to build my eForth
in C. It is a daunting task because thisForth uses the M4 macroprocessor to
build its C program. I even called Wil and can report that he is in good health
at 81. I was able to delete all the optimization Wil put in thisForth, and kept
it working. I will discuss how thisForth was constructed and some of its
internal structures."

Lunch
Lunch on-campus. To avoid the "noon lemming effect", we'll leave a
little early.

Consensus-based Detour:
New Guinea Sculpture
Garden
On the way back from lunch we might detour to this interesting collection. (If
we decide to do this, add 12 minutes to the start time of all items below.)

Rational Representation of the
Irrational - LaFarr Stuart
LaFarr will say something about a couple different "words" that he
thinks would be interesting in a stack-oriented language and possibly a bit
about finding best fractions such as: 22/7 or 355/113 for Pi based on Continued
Fractions (which involve pretty complicated mathematical proofs; but there are
relatively easy ways to use the result, even with just a pencil and paper).

Running FIG-Forth on Simulated National
Semiconductor PACE and IMP-16 Processors - Eric Smith
Eric will present further discussion and demonstration of FIG-Forth running on
a PACE simulator. Since last month, he's rewritten the simulator in C (it was
in Java before) and added a simulated disk. He has started work on converting
PACE FIG-Forth to an IMP-16 FIG-Forth with the eventual goal of running it on a
"real" IMP-16 system.
