Device-Independent Programming

Each device type supported by GT.M responds to a particular subset of deviceparameters, while ignoring others. Devices may be programmed in a device-specific manner, or in a device-independent manner. Device-specific I/O routines are intended for use with only one type of device. Device-independent I/O routines contain appropriate deviceparameters for all devices to be supported by the function, so the user can redirect to a different device output while using the same program.

GT.M supports the following I/O device types:
