 Below is a list of FORTRAN-20 logical unit assignments. For file input or output, you may use any of the units assigned to disk (0, 1, 20-24, 30-99). If you do not specify a file name when you open the logical unit, FORTRAN-20 will use the default file name (in your currently connected directory) corresponding to the unit you are opening as shown in the table. Below is a list of FORTRAN-20 logical unit assignments.
