I don't believe that '$' is required to scan as anything. Since it is not in the C source character set, a conforming compiler is under no obligation to do anything in particular with it and so is at liberty to do anyting at all with it. If an implementation chooses to allow it in identifiers, that's fine (although it should diagnose the syntax violation - perhaps by congratulating you for seeing the value of using names containing dollar signs). ---- Larry Jones UUCP: uunet!sdrc!scjones SDRC scjones@sdrc.uucp 2000 Eastman Dr. BIX: ltl Milford, OH 45150 AT&T: (513) 576-2070 "Save the Quayles" - Mark Russell
