This Natural profile and session parameter can be used to prevent an internal REINPUT for invalid data.

Possible settings	ON	An internal REINPUT statement is issued when invalid data have been entered.
	OFF	An internal REINPUT statement is not issued when invalid data have been entered.
Default setting	ON
Dynamic specification	yes
Specification within session	yes
Applicable statements	SET GLOBALS

Notes:

1. By default, Natural automatically issues an internal REINPUT statement if invalid data have been entered in response to an INPUT statement. With this parameter, you can switch this mechanism off. This will allow you to handle such input errors yourself in your application.
2. Within a Natural session, the profile parameter REINP can be overridden by the session parameter REINP.
