UPT

The logon processor passes to the exit a UPT that contains binary zeros. The exit can update and return the UPT to the logon processor in the UPT parameter. If the exit returns an updated UPT, it must also set either of the following bits on:

The UPT bit, or
The Don't Prompt and the No UADS bits

Note: If the exit passes the UPT back but leaves the length or version fields zero, these fields are filled in by logon. If the primary or secondary language translation fields are left null or blank, the logon defaults them to ENU for mixed case U.S. English. If any of these fields are filled in by the exit, their validity is determined by the exit. For a description of the UPT, see .
