OFTO keyword

Allows you to control when output from validations occurs, so that output that is intended as default values in other fields does not replace data the user has entered.

OFTO (OutputFirstTimeOnly) means that output from the validation (either SETP/V/C, or output parameters from methods) should only be done the first time, where first time means the first time since this object was loaded into the collection, or became the current instance via navigation.
