This chapter describes the following topics which relate to input and output processing:

OPEN, USE, and CLOSE commands accept deviceparameters, which are keywords that permit a GT.M process to control the device state. Some deviceparameters accept arguments, and some require them. The current ANSI standard for GT.M does not define the deviceparameters for all devices. This chapter includes descriptions of the GT.M deviceparameters in the sections describing each command.
