There was an internal call for Sort but it did not produce a program name.
DBO8907I INVOKING SORT UTILITY.
DBO8915E UNABLE TO LOAD THE SORT UTILITY.
Even though it does say "SORT" it's hard to tell if it's IBM sort or Syncsort being called but according to Syncsort it hasn't made a call to Syncsort and since this is an internal program call it's the vendor with the program call. We on the other hand have two sorts running, IBM's DFSORT and Syncsort.
For clarification, why can't the CA IMS-Tools Data Base Organizer provide the PGM by name, rather than just by SORT?
