13.1.3 RDML Screen Modes and Mode Sensitive Commands
The DISPLAY and POP_UP commands cause information to be displayed on a workstation. In addition the "mode" in which the information should be displayed can also be specified. Currently screens can be displayed in 4 different "modes" that are referred to as:
- *DISPLAY mode
- *CHANGE mode
- *ADD mode
- *DELETE mode
The processing mode which is in use when a DISPLAY and POP_UP command is executed affects:
- Whether or not fields on the screen can be changed by the user.
- The function keys that are enabled.
- The processing logic that is used by the DISPLAY and POP_UP commands.
The screen mode can be set / changed by using the SET_MODE command and can be tested using the IF_MODE command.
