Yes, I was using an early version. Back then Orca C was K&R syntax, with various bugs/problems. Looking at the cc.notes for 2.2.0 B1, it appears that the latest Orca C is a very different compiler, with C89 and some C99 language features and tons of improvements.

I purchased the Opus ][ collection a year or so ago but haven't installed the Orca shell & dev environment yet to try it. I'll have to move that up the priority list so I can play with the new Orca C.
