Forth

[Bob Shannon]

I'd love to get some feedback from an experianced Forth user.

Especially one who has an HP1000 CPU needing software.

As a HP collector I've long wanted a portable software tool I could used to 
bring
up and actually use machines with at little as 4K words of core.

I'd read about Forth and (correctly) decided that a threaded interpreter 
would be
the most practical approach.  I read 'Threaded Interpretive Languages..." 
and saw
that the psudocode for the 'generic' inner interpreter ~was~ HP assembler 
with a
few subroutines to implement stacks.  Odd for a machine without a stack, 
but...

So another HP fan and I built a threaded interpreter that is clearly NOT 
Forth, but
it is Forth-like.

Forth itself was just too terse, but seductivly efficient.  IPL has a number 
of structural
differences from Forth, and it would be helpful to hear a Forth user's 
thoughts.
