[Mono-list] writing an interpreter in c#

[Derek Gottfrid]

i developed a small language  in c# as well. i started with coco but ran
into
problems. running the coco executable against your grammer spec under mono
appears to work but after much frustration i realized that the combination
of mono + coco produced incorrect code. worked fine under windows and the
msft clr. i didn't venture much further after that experience with coco
and switch instead to antrl - antrl supprot for c# and mono seems way
beeter plus overall antrl appears to be a more complete product. anyway i
would be interest to here what progress you make. good luck.

enjoy
derek
