Location 4 means address 4 (i.e. offset 4 in the PSA). There was a latent bug from a prior release in the loop control code so that it was erroneously fetching from address 4, and behaving especially badly when the data at that location is x'00000000', which it is as of z/OS 2.5. In prior releases, it was x'000130E1' when in zArchitecture mode. Jim Mulder z/OS Diagnosis, Design, Development, Test IBM Corp. Poughkeepsie NY
