I posted this question a while ago, and not even "jax" responded, so
I'll try it again...

I've seen Forth systems that generate object code.  How is usually done ?
Inline code ?  Lots of jsr (subroutine calls) ?  Are they simply using
the dictionary as a "symbol table" ?

I'm interested in any discussion at all on this, if you don't know how
it IS done, how would you do it ?

It seems to me that storing assembler mneumonics for each dictionary
word and simply generating inline code would work, but I'm sure there
are other algortihms.  Also, some flexibility is necessary I'm sure
because pure inline expansion of all words would yield HUGE code.

Any ideas ?
