Thanks, Maarten, that's good to know. I've been using a macro assembler that came with an earlier version of SDCC, or, perhaps (I don't recall), was simply pointed to by one of the related sites. It has a good help file which has saved me many an error, and it's part of the "MIDE" package, which includes a simulator and claims to hook up in some way to SDCC. That may be why I made some possibly unwarranted assumptions about its relationship to SDCC.
