Category 18, Topic 48 Message 2 Sat Feb 10, 1990 M.HAWLEY at 22:48 EST COMMA ( , ) reserves one word ( 2 bytes ) of memory and stores the number on the stack into that memory location. Example: CREATE MY-ARRAY 123 , 229 , 12345 , 77 , Now to access that data, MY-ARRAY 2+ @ leaves 229 on the stack, at least this is the way it works in F83 and F-PC C, is the equivalent single byte word.

I found the same bug in s*p*a*c*e fig forth and ELCOMP's Power-Forth, two other fig dialects. Is this bug common to all 6502 fig FORTHs? Is it longstanding common knowledge or did I discover something? The bug is easily patched; it's a missed carry in the code definition. NET/Mail : DC Information Exchange, MetroLink Nat'l Hub.

I fool around with it every so often and I know there are some questions I have about ValForth that I have never gotten good answers about. By the way are the originators of ValForth still out there someplace working with Forth? ----- This message came from GEnie via willett through a semi-automated process.

Subj: ATARI VALFORTH Status: PUBLIC MESSAGE
Valforth was the best Atari implementation I ran across (and the
most expensive) but having paid for MVP before it was free it was also a
very good implementation. It was improved several times after I made
the initial investment in Valforth and before it was free so it should
be most of what anyone would want.
This is a five year old comment now, but the more interesting
words of Valforth leading to control of the screen modes, joysticks, PM
graphics and such were not in any particularly way better or worse than
the ones I wrote to replace them. How do we say this right. They were
simply implementations for completeness rather than marvels of elegance
and simplicity that elicites the comment "why didn't I think of that."
