- Entry:
- ACP1 or ACR1
- VIT option:
- APPC
- Event:
- LU 6.2 user post or RPL exit (Part 1)
- VIT processing module:
- ISTRACAC
- Control is returned to:
- ISTAICPT and ISTAPCSX for ACP1
ISTAPCSX and ISTAICRX for ACR1
The ACP1 trace record is written when an ECB is posted.
The ACR1 trace record is written when an RPL exit is dispatched. These
records signal that the APPCCMD macro has completed execution and
show the data returned to the user application program.
