  Small code for switching NUMLOCK on and off
  written in PowerBasic 3.20
  by Rolf Genster on 01/19/96

  Bit 6 : Caps Lock
  Bit 5 : Num Lock           1 = active, 0 = off
  Bit 4 : Scroll Lock


  Code for MS-Basics would look like:
       POKE &H417, PEEK(&H417) OR 32       'NUM-Lock on
     or
       POKE &H417, PEEK(&H417) AND NOT 32  'NUM-Lock off
