I recieved my copy of MacForth on Friday. I have read the manual and
played with the demos. It fun, its fast, its a hackers delight. Forth
is the Mad Hatter of programming languages. The distribution comes
with a primes program, it counts the primes from 1 to 8K in about 2 seconds.
L* it isn't. I'll write a longer review once I've actually written a
program.
As an aside, it doesn't seem fair to broadcast bugs in MacPascal's
prerelease versions. ben.
--- A little program in MacForth for an etchastech ---

" My etchings " etch.window w.title

ps. I wouldn't buy this unless you have skimmed a book about
forth, and you are willing to skip getting into computer science
heaven.
pps. The above program is probably covered by their copyright.
