When you generate a COBOL program, the returnTransaction build descriptor option identifies the IMS/VS or CICS® transaction that starts when the transaction associated with the EGL-generated program ends without a transfer.
This option is effective at run time only if the option is specified for the first program in the run unit. You usually use this option when a menu-driven program starts the run unit and you want to return to the menu.
For CICS, only four characters are processed; if you specify more, the fifth and later characters are ignored.
If you do not specify returnTransaction, the user's screen is cleared when the program ends and does not transfer. For IMS/VS, if you want to avoid clearing the screen, assign EZENOINS to the build descriptor option.
