The restart field statement begins processing on the current field again.
restart field
None
This statement is useful for fields whose values need to be validated before they’re accepted. The difference between this command and the focus statement is that the focus statement can move the focus to other fields, and always runs the post script of the current field and the pre script for the new field. The restart field statement in a change script doesn’t run the post script and the pre script for the current field.
