We are attempting to run GJTRJPRG on our Sysprogs 'sand-pit' z/OS system using SYSIN: EVENT=*,GEN=1,DAYS=30,DELETE STTDAYS=30 AUDDAYS=30 IPLDAYS=30 This abends S0C7 at offset 284 in GJTREVST. As this is a sand-pit system it is unlikely that regular 'house-keeping' has been performed on Jobtrac (as is done with other systems where Jobtrac is deployed and used) so this might be that GJTRJPRG has not been run for years on this system. This might be a factor in this problem.
I had a 'rogue' load library in the STEPLIB concatenation of the job which contained some very old Jobtrac modules; this was ahead of the currently deployed Jobtrac load library in STEPLIB. I removed this library and re-ran the job without problem
