DISABLE FIELD FOR INPUT

Execution

PERFORM RMP--DFI-PANELNAME

Description

This standard runtime function prevents input to a field/control that was specified as allowing input in the Panel Editor. Many times a certain field/control should be input, or not input, based on the value of another field/control. This standard runtime function allows a field/control to be disabled for input at runtime execution, rather than at panel creation time, increasing the flexibility of the EXECUTE EVENT standard runtime function.

Required Parameters

The program must set the name of the field/control to be disabled in RMP--FIELD-NAME. If the field/control occurs more than once, all occurrences of the field/control will be disabled.

Optional Parameters

RMP--SUPPRESS-EVENT-RESET can be set to TRUE to prevent RMP--NEXT-FIELD and RMP--NEXT-OCCUR from being reset.

Returned Values

The values of RMP--NEXT-FIELD and RMP--NEXT-OCCUR are reset, based upon the new input status of the fields/controls on the panel.

Additional Usage Notes

This standard runtime function resets the next field/control to be entered because generally the standard runtime function is used within an event loop and the new input status of the field/control should take effect immediately.
An inverse standard runtime function, ENABLE FIELD FOR INPUT, is also available.

RMP--STATUS Values

Status value	Description
0	The function executed successfully.
1	The field/control name is invalid.
5	The panel is not in this library
6	The library does not exist.
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.
