[my RatForth language description]


>[Gee, sounds not altogether like bc, the C-ish front end to the RPN dc. -John]


Don't you mean unlike (grin)? [sure, we Old Farts can't type -John]


Until this moment the similarity to bc/dc didn't occur to me. It's obvious
now I think of it.


The implementation, though, was in Forth. The word "define" was a Forth word
that compiled ratforth into a buffer until it ran out of matching braces, so
you could mix ratforth with forth interchangably:


: this blah blah blah ;


define that { blah blah; blah; }


I generally used Ratforth for complex expressions, and you could take
obscene advantage of the implementation. For an example:


define peek { @(2+dup()) }


Becomes:


: peek dup 2 + @ ;
