HPIO control statement

Specifies whether to use the High Performance I/O Driver in the Reload task and the Image Copy task.

This control statement is optional. HPIO=xxx specified in the (REORG) block overrides the HPIO control statement in each subtask.

If you do not specify this control statement, the value for the HPIO option is determined as follows:

  • If the libraries specified on the STEPLIB DD statement are not APF-authorized, HPIO=NO is used.
  • Otherwise, the HPIO option of each subtask is effective.
