Because LRF commands have the potential to be much longer than CA IDMS DML commands, a new optional format for the static part of the screen is available to deal with LRF commands. The new format may be selected using the SET LRF ON/OFF command.
CA IDMS DMLO, CA IDMS DML, and LR commands may always be entered in the MENU/ASSIST Mode or standard screen formats; the larger command area in the 'LR' format is available if needed.
To enter commands longer than the available command line(s), use the EQUATE phrase capability of CA IDMS DMLO to create a shorthand form of the command. The expanded command length may exceed the input area length.
Note: The LRF screen is applicable not only for LRF commands, but may be used whenever an expanded command area is needed.
