1432	 Incorporation of Nonstandard Input Output Devices into FORTRAN Systems	 A FORTRAN system may readily be modified to handle input output with nonstandard media on the same basis on which it handles the standard media. This is done by providing a character-handling subroutine suited to the nonstandard medium and arranged to be called by an otherwise unused output statement type or unit number. This method was used to control output of alphanumeric information on a digital graph plotter.
