The indicator combinations of CMB, CIB, CSB, and CEB handle pre-processing of Command Line commands entered at the top of the Menu, Identify Table, Edit Table, and Edit Row screens, respectively. Control is transferred to the exit program after the command line contents have been parsed and translated (using the TBOLCMDS translation table) into T-COMMAND and T-CMD-PARM before they are executed by tablesONLINE/CICS. This is useful for validating user authorization for particular tablesONLINE/CICS commands, enhancing the operation of tablesONLINE/CICS commands, or for creating entirely new commands.
If you are processing commands that are foreign to tablesONLINE/CICS, you must set the T-COMMAND field to spaces or any valid tablesONLINE/CICS command to avoid the generation of an invalid command error message.
