This standard runtime function alters the enabled attribute code assigned to a field/control through the Panel Editor. The attribute value remains altered until the panel is removed. This standard runtime function allows a field/control to be displayed with different attributes based on its value or other runtime system conditions.

Required Parameters

The program must set the name of the field/control to be changed 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.

RMP--ATTRIBUTE must be set to space or to a value in the range A through P to indicate the new attribute for the field/control. A value of space restores the default attribute value.

Additional Usage Notes

  • Before this standard runtime function can be executed, the panel must be displayed.
  • This standard runtime function displays the field/control with the new attribute. However, if it is a repeating field/control, it displays only the specified occurrence. Setting RMP--FIELD-OCCUR to 0 displays 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.
4 The attribute 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.
