UP entry for user application program post

Entry:
UP
VIT option:
API
Event:
User application program post
VIT processing module:
ISTRACAP
Control is returned to:
ISTAICPT or ISTAPCSX

This trace record provides the RPL information that VTAM® passes to the application program. The RPL information and the API TPIO request record (AIn or IOn) show VTAM activity for a given API request.

See z/OS Communications Server: SNA Programming for a description of the RPL return codes.

If this entry is associated with an event failure (that is, the return code is nonzero), this entry is generated whether the API option is in effect. It is treated as an exception condition, and is always traced if the VIT is active, regardless of the VIT options specified.
