For changing controlpad settings fromout scripts, you may
 use the SVPrefs command (SYS:Prefs/SVPrefs), which not only
 offers a nice GUI, but can be used from CLI/Shell or ARexx, too:

  Syntax:  SVPrefs SET file NAME [VALUE]

  Examples:

    1. Set 24BITOPERATOR=Dither24Bit in ENV:SuperView-Library/AGA.controlpad

       SVPrefs SET AGA 24BITOPERATOR Dither24Bit

    2. Set keyword SCREENINFRONT in ENV:SuperView-Library/AGA.controlpad

       SVPrefs SET AGA SCREENINFRONT
