This standard runtime 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.

Note: While much more powerful than a standard DISPLAY statement, this standard runtime function is not the preferred method of displaying field/control values in RM/Panels. Use the DISPLAY ALL FIELDS and DISPLAY PANEL standard runtime functions as the primary method of displaying field/control values. Use DISPLAY FIELD when only one field/control is to be displayed.

Required Parameters

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.

Additional Usage Notes

  • Before this standard runtime function can be executed, the panel must be displayed.
  • Setting RMP--FIELD-OCCUR to 0 will display all occurrences of a repeating field/control.


Status value Description
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.
