Initial settings of the TBLBASE command area

When invoked directly as a transaction, DK1TDRVC initializes the TBLBASE command area with spaces or low-values, as appropriate.

When invoked by tablesONLINE/CICS, DK1TDRVC initializes the command area using data supplied by tablesONLINE; specifically, DK1TDRVC will display the name of the last table, the command, and the error code processed by tablesONLINE. This facility is particularly useful when debugging exit programs. If you want to set up tablesONLINE/CICS to exit into DK1TDRVC whenever the Clear Screen key is pressed, please see the section on Menu Tables in the tablesONLINE/CICS User’s Guide.
