Exit XZCOUT

This exit is invoked before an output event.

When invoked
Before an output 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.
Note: In certain circumstances—for example, when XZCOUT is invoked before the send of a NULL RU—UEPTIOA contains zeroes.
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.
