Deleting Records via an Interface
The form load can also be used to delete records from a form. In fact, the very same interface definition can be used both to insert/update form records and to delete them, the sole difference being the definition of the record type in the load table or file.
Note: If you use the form load to delete records, make sure that you don’t flag the Replace Form Data column in the Forms to be Loaded form, as this will cause the form load to fail.
To delete records from a form, record @ before the number value assigned to the record type.
Example: See the POST-FORM2 trigger in the ORDERITEMS form, which deletes irrelevant lines from the form.
