UEPTPNL
Address of a 1-byte field containing the length of the TPN or DPN.
UEPTRAN
Address of the 4-byte transaction ID.
Note: The exit program must not change the TRANSID of tasks
started by automatic transaction initiation (ATI). (This is
because CICS needs to match the TRANSID in its program
control table with the TRANSID in the automatic initiate
descriptor (AID) that was created in the AOR.)
Return codes
UERCNORM
Continue processing.
XPI calls
All can be used.
VTAM working-set module exits XZCIN, XZCOUT, XZCOUT1, and
XZIQUE
Note: None of the exits in the VTAM working-set module is available for advanced
program-to-program communication (APPC, or LUTYPE6.2) links.
Exit XZCIN
When invoked
After an input event.
Exit-specific parameters
UEPTCTTE
Address of the terminal control table terminal entry (TCTTE). The
TCTTE can be mapped using the DSECT DFHTCTTE.
UEPTIOA
Address of the terminal input/output area (TIOA). Your exit program
should not change the address. The TIOA can be mapped using the
DSECT DFHTIOA. However, fields TIOASAL and TIOASCA are not
programming interfaces.
Return codes
UERCNORM
Continue processing.
XPI calls
All can be used. However, we do not recommend that you use a GETMAIN
call to obtain terminal-class storage for use as a replacement TIOA. This is
because there are several internal pointers to the TIOA, and if any one of
these is not updated the application may experience problems.
Exit XZCOUT
When invoked
Before an output event.
