The reason I got involved is that you made it seem like an obvious thing. It isn't always bad to index. Back in 1989 I sat in a conference room and listened to the Microsoft C guys tell us how you could now write array indexing code without worrying about it. This was not strictly true, but things did get a lot better. >I remember some years ago i had diep like nearly 10% faster when i mixed >chars with 32 bits integers. that's hell faster still today at all processors, >but i simply rewrote everything to integers and i am more happy about it >because i don't need to remember now whether something is 8 bits or 32 bits! I agree with this. I think you are in better shape if you try to confine math operations to "natural" types such as "int" and "unsigned". bruce
