Value

Meaning

Screen Level (default)

The entered values are edited/validated once the entire screen is entered.  Note that even if a host validates on a per-field basis, this setting will still work and is appropriate when the error rate is low, as the only downside of this setting is that when an error occurs it may take a few seconds longer to detect compared to custom field-level checks.

Field Level

Entered values are edited by the host on each field entry.  Generated code may include waits for the cursor to indicate a clean data entry.
