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.
UEPTCTLE
Address of the terminal control table line entry (TCTLE). The
TCTLE can be mapped using the DSECT DFHTCTLE.
