PAINTWIN [ expression ]

   Synopsis:
      Changes the task window's colour scheme

   Notes:
      Some task windows (such as the one used by the Locator task) use a variety
         of colours on a black background. Other task windows (such as the one
         used by the Status task) use several different background colours, with
         the text colour automatically set to match.
      The Script task window behaves like the Locator task window, by default.
         However, this statement changes the window's background colour so that
         it behaves more like the Status task window.
      If specified, the expression must be one of Axmud's standard text colour 
         tags, namely "black", "red", "green", "yellow", "blue", "magenta", 
         "cyan", "white". Any of these colours can be specified IN CAPITALS to 
         make them bolder (e.g. "RED", "GREEN").
      The text colours is automatically changed to match the background colour.
         Any colours specified by earlier WRITEWIN statements are lost.
      If no colour is specified, the default colour scheme is used.
      
      If the Axbasic script isn't being run from within a task, or if the task
         window is not open, the PAINTWIN statement is ignored (and no error
         message is generated). Execution continues immediately with the next
         statement.
      Axmud underlay colours such as "ul_red" and "UL_BLUE" can also be
         specified; the corresponding normal colour is used.
         
   Examples:
      PAINTWIN "white"
      PAINTWIN "CYAN"
      PAINTWIN
