If value is Yes, the key becomes a termination key that also causes the AT END condition. This keyword may not be specified along with either the TERMINATE or EXCEPTION keywords. The AT END condition always returns a termination value of -1 in the CONTROL KEY clause. AT-END keystrokes are always allowed, but will cause no action unless an AT END, EXCEPTION, or CONTROL KEY clause is present in the ACCEPT verb. The default keyboard defines no AT-END keys. See also the AT END phrase of the ACCEPT verb in the ACUCOBOL-GT Reference Manual, Procedure Division.
