Program Event Recording (PER)

The PER user exit, UPER, is called by system error processing. This exit provides a means of changing the output destination for data captured by a PER interrupt. This exit also permits changes in the amount and/or format of the interrupt data displayed.

Input

D0
PER data block

Programming Considerations

  1. The identification of the alternate destination must have been specified when PER was activated. The ZSPER command provides the PRINTER parameter for this purpose. The value specified for PRINTER parameter is passed to UPER with the PER interrupt data. The programming required to support this option is a customer responsibility.
  2. UPER contains sample code that formats the PER interrupt data and prints it on the RO CRAS.
