Echo OFF
Echo      This file will print a copy of an invoice for you to use in
Echo      registering a copy of TUTOR.COM.  The file will be printed
Echo      on your default printer (device PRN) if you did not specify
Echo      any other printer when you start this batch file.  As an
Echo      example, if you wanted the invoice to print on a printer
Echo      attached to your first serial port, you would start this
Echo      batch file with the command:     INVOICE COM1
