When adding a FILE level validation check to a field, the file involved must have been previously placed into an edit session by the START_FILE_EDIT Built-In Function.

All argument values passed to this Built-In Function are validated exactly as if they had been entered through the online validation check definition screen panels.

Normal authority and task tracking rules apply to the use of this Built-In Function.

For more information refer to Field Rules and Triggers in the LANSA for i User Guide.

Þ This is a Specialized Built-In Function for use in a Development Environment only.
