Printing Results

Most of the routines in the IMSL MATH/LIBRARY (except the line printer routines and special utility routines) do not print any of the results. The output is returned in Fortran variables, and you can print these yourself. See Utilities for detailed descriptions of these routines.

A commonly used routine in the examples is the IMSL routineUMACH (see Reference Material), which retrieves the Fortran device unit number for printing the results. Because this routine obtains device unit numbers, it can be used to redirect the input or output. Machine-Dependent Constants in the Reference Material contains a description of the routine UMACH.
