Library /sys$common/syshlp/basichelp.hlb Graphics, SET Statements, CLIP  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The SET_CLIP statement lets you change  the  status  of  the  clipping
  rectangle  in  the world viewport.  The clipping status must be set to
  either "ON" or "OFF".  At the start of program execution, clipping  is
  set to ON.  For more information on clipping, see the Programming with
  VAX BASIC Graphics manual.

  Example

  PROGRAM display
    EXTERNAL PICTURE BASIC_flag
    SET WINDOW 0,100,0,100
   Screen1:
    SET CLIP "OFF"
    DRAW BASIC_flag
    SLEEP 4%
    CLEAR
   Screen2:
    SET CLIP "ON"
    DRAW BASIC_flag
  END PROGRAM
