The VALIDATE action attribute defines the data validation level for a given action.
Syntax 1 (Dialog action handlers and form action defaults)
VALIDATE = NO
Syntax 2 (Global .4ad action defaults file)
validate = "no"
When the VALIDATE action attribute is set to NO, it indicates that no data validation must occur for this action. However, current input buffer contains the text modified by the user before triggering the action.
This attribute applies to the actions defined by the current dialog in the current window. It can be specified as action default attribute in a global .4ad file, in the ACTION DEFAULTS section of form files, or as dialog action attribute.
