                This file name is built from the current date by the
                Sales init code, and has the format MMDDYY.TOT.  This
                is used so that if you exit the program, the sales thus
                far for today are not lost.  If the file exists when
                Template() starts, the old totals are read in.  The file
                is always created with the latest data when the program
                ends.  This is accomplished with the Close() call (if
                this call is made several times, the file is just
                updated each time).
