This standard run-time system function displays the value of a single field/control on the panel. It is similar to a standard DISPLAY statement, except that RM/Panels sets all the parameters. Many characteristics of the field/control can then be modified solely through the Panel Editor, without requiring program changes or recompilation.
The program must set the name of the field/control to be displayed in RMP--FIELD-NAME. If the field/control occurs more than once, the occurrence number must be specified in RMP--FIELD-OCCUR. The occurrence numbers are equivalent to COBOL subscripts and begin at 1.
|0||The function executed successfully.|
|1||The field/control name is invalid.|
|2||The occurrence number is invalid.|
|5||The panel is not in this library|
|6||The library does not exist.|
|10||The panel is not displayed.|
|14||A COBOL input/output error was encountered on the panel library during execution of this function. To determine the exact nature of the I/O error, use the C$RERR subprogram.|
