I looked at that, and it was a toy language.
Alas most of the languages I   want to  use, still  have  commerical 
copyrites on them, or the OS
or the source has been lost years ago.
The cpu I have designed does not lend itself to the simple compilers 
that produce a stack based
instruction set.  a - *n   compiles to:  load a, st --*sp, load n,  st 
--*sp , load **sp,  reverse subtract *sp++.
I want to generate is ld ac a, sub ac @ n.
