≫ Little argument other than the economic balance between silicon and carbon, counting learning in the latter. How much data?
Paul, Take a simple of case less than or equal to 5 Million records. You can run a test and see for your self as to how much it takes to do the same using REXX vs DFSORT. >> ... address LINKMVS DFSORT ... Aren't you invoking DFSORT from REXX? I think you skipped reading the text in BOLD " 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" ≫" ... everything looks like a nail." (Yes, to Bob and me also.) We can debate about it, but in the end, if someone asks for a DFSORT solution and if it can be done using it, then I will try to post which would show case the rich features available with the product.
