Bob, Rexx is a handy tool, but it performs poorly against huge volumes of data. Moreover you need to have the Data SORTED before you can calculate the deltas and you need to invoke SORT or have a separate step to sort the data, as you cannot load the entire file into a stem. If you are sorting the data using SORT, why not calculate the delta there itself?
