TLMSXTRS - Tape Retention System Exit

TLMSTRS passes control to a user-written exit routine (TLMSXTRS) at two places; preprocess (before the retention process), and scratch process (after TRS has determined the volumes should be scratched).

TLMSTRS calls this exit using standard operating system linkage. Register 1 points to a parameter list which contains

• Preprocess (one entry)

  address of the VMFBASE or VMFMDS record

• Scratch process (two entries)
  • address of the TLMSTRS work record
  • address of the TLMSXTRS message CAT4550E (60-byte user message)

This exit is activated by specifying YES or exitname in the TRSEXIT system option.
