One use of field conditions is to check that the value entered for a field is valid during data entry. This is done by specifying a Check condition. By default, no field validation takes place. This is indicated by *NONE for the Check condition field on the Edit Field Details panel.
A horse’s gender can only be one of two values: male or female. Conditions to check for these values can be attached to the Horse gender field of the HORSE file as follows.
