The program is self-contained, no special compiler switches or external libraries are required. Tested using Intel Visual Fortran v 8.0 running in a Microsoft Windows XP operating system. After commenting out the AFILE subroutine (see below), the code also compiled using the f90 and g77 compilers on a Sun computer (Unix operating system) and using g77 on a system running RedHat Linux. The subroutine AFILE (line 836 of the program) allows the program to get the names of the input, output, and plot files from the command line. It has compiler-specific library calls. The code has the commands for Lahey and Intel compilers. To re-compile the program, comment out the lines that are not needed. If the option to get the file names from the command line is not desired, comment out the entire subroutine and the call to AFILE on line 106. If line 106 is commented out, IPLOT must be set to -1 (or other coding used to have the program call OFILE, line 109). Program requires input data file described in the documentation to run. An example data file is included with the download zip file.
