     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
It can sometimes be useful to control the Shift or Caps Lock from within a
program, to ensure that the machine is set correctly for the next INPUT or
GET statement. This can be done with the command *FX202,n, where n is as
follows:-

 16 - Shift Lock  On     144 - Reverse Shift Lock On
 32 - Caps  Lock  On     160 - Reverse Caps  Lock On
 48 - Both  Locks Off
