EQQCLEAN GDG resolution exit (EQQUXGDG)

EQQUXGDG is invoked by the EQQCLEAN program just before executing any single GDG overwrite action into JES control blocks. The overwrite action will not be executed when the EQQUXGDG return code is set to a value different from 0.

The provided exit sample prevents the GDG overwrite action for a job with jobname MYJOB and the DDNAME is NOSIMDD or GDG data set name starts with TST.GDG.
