     To use the TC calculator simply type tc at the dos prompt and press
     enter.  Pressing the e or the esc key will exit the program, but
     your work will still be on the screen.  Use the asterisk or shift
     8 key to multiply.  Use the / key to divide.  If you are not
     multiplying, dividing or subtracting, the enter key is the same as
     pressing the + key.  Pressing the enter key twice is the same as
     pressing the = key.  Pressing the c key will clear the total.  The
     default setting is for two decimal points.  If you need the
     calculator to be more precise, start the program with the number of
     decimal points that you need such as tc 5
