All of these files need to be put into the same folder. The file that you run in Gauss is moneea.prg - this programme calls on the other procedures. You will need to change the file paths listed in moneea.prg, and note that the dforrt.dll file needs to go into the Gauss directory. All other documentation is in the code itself. There may still be errors in this code - Use at your own risk !! & Please let me know if you find any problems. Note that this code may be revised without notification.
