$$KEYVAL^DIE: Key Validator |
|
The Key Validator extrinsic function
verifies that new values contained in a FileMan Data Array (FDA) do not produce
an invalid key. All keys in which any field in the FDA participates are
checked. If the value for a field in a key being checked is not present in the
FDA, the value used to verify the key is obtained from the previously filed
data. |
