FORTH Beginner Question.

[Garth Wilson]

Are you giving GROW the quantity parameter on the stack? I don't have that module but rather the other Forth module (HP82441A), and it works fine.

The HP82441A was my entry into Forth as well, and I had the book "Starting Forth" which I bought from EduCalc. The manual for the Forth module assumed you already spoke Forth and only needed to know the particulars about how it works on this systems with a 4-bit data bus and a 20-bit address bus and word length of five nybbles, and the book assumed you had something to practice on; so they were left pointing at each other. I did eventually get going though. The Forth provided by HP was not a very good one; but since it's Forth, I was able to expand and improve it a lot. I timed and re-wrote a lot of the built-in words, achieving, in the extreme case (of CHR$), a 14x improvement in speed, without resorting to assembly language.
