That would be a perfect candidate. Low source file count, compact in core [depending on dynamic requirements]. Easily modifiable for the task, and looks to have a usable base subset of the language. > $ cd ~/lang/Scheme/tinyscm-1.27 > $ size scheme > text data bss dec hex filename > 61342 4476 3480 69298 10eb2 scheme > $ wc *.h *.c > 12 33 247 dynload.h > 344 1136 9221 scheme.h > 126 292 2589 dynload.c > 4445 12353 125421 scheme.c > 4927 13814 137478 total > > Tinyscheme is a mostly complete R5RS Scheme (R5RS is the > closest thing to a Scheme standard) -- everything except > complex and rational number types, bignums, hygenic macros > and call-with-values and unwind-protect.

It's a niche language that has few proficient programmers. LISP may not be "mainstream", but it's far more so than Scheme [or FORTH for that matter], and is commonly taught in CompSci classes, meaning that most serious programmers have at least been familiarized with the language, in fact, your local drating tech may be quite proficient in it [AutoCAD uses LISP]... I personally don't care if FORTH stays, but if it's up for debate, LISP is a great choice. jim -- ET has one helluva sense of humor!
