OPF - Overwriting of Protected Fields by Helproutines

This Natural profile and session parameter specifies whether the content of a write-protected field (attribute definition AD=P) can be overwritten by a helproutine assigned to the field.

Application programming interface USR1005N See SYSEXT - Natural Application Programming Interfaces in the Utilities documentation.


  1. The OPF profile parameter only applies to the field for which a helproutine is invoked; it does not affect parameters explicitly passed to the helproutine. This means that the OPF profile parameter takes no effect if the field for which help is invoked is also explicitly specified as a parameter to be passed to the helproutine.
  2. In addition, in reporting mode you can change the OPF setting using the statement SET GLOBALS.
  3. Within a Natural session, the profile parameter OPF can be overridden by the session parameter OPF.
