Rewrite them into COBOL? <grin> The REXX compiler would likely be helpful. But if, like me, you're stuck with using normal, intepreted, REXX, then about the only thing you can do is try to do as few operations as possible. Likewise, try to use powerful functions instead of simplier ones. They'll be less intepretive overhead. Lastly, and likely most important, review your code design. Many years ago, on a pre-IBM personal computer (z-80 based), I wrote two sort routines. One in assembler and one in intepreted BASIC. The assembler was a "bubble sort". The BASIC was a Heap Sort. Believe it or not, the BASIC program outperformed the assembler one. Due entirely to the fact that a HeapSort is much more efficient than a bubble sort. So, using an efficient algorithm can really help.
