Re: Pointer vs. BIF performance

charPtr += 1;

Bruce, there's a slight risk of a pointer-offset error with that approach. The final increment of the pointer positions it beyond the end of the variable. If the SRCDATA variable happens to lie at the end of a physical storage segment, you'd get MCH0601 on the last loop iteration.
