'BIGNUMS.BS2 (Display four 1" digits on 4x20 display)
' Connect the serial input of a Backpack-equipped 4x20 display to
' BS2 pin P0 and run this program. The program will define a set
' of symbols that allow it to display 4-line-tall numerals on the
' LCD. To incorporate this capability into your own programs, just
' substitute your code for the demo loop. When you want to display
' a value (0-9999) in big numerals, write it to dispVal, then
' gosub bigLCD.
