I think that might be a typo, try: b'01010010' Steve >>> dwheeler@INSIGHTEK.NET 6/3/2004 8:36:10 AM >>> I'm a bit embarrassed to ask this but how does one represent a binary number in C30. Page 2 of the C30 users guide claims 'b01010 and the like should be OK, but I can't seem to get the compiler to be happy with it. I'm sick of converting to hex notation...
