Thanks for the info. The DIFERROR values were useful. SDTODIF still won't run, but I now know it's due to DIFERROR 18, "SD intrinsic call failed." Guess it's because of missing SL segments. Maybe SDTODIF was officially part of something like Information Access or HPListKeeper and as best I know, none of those old products were ever installed at my site.
