  id=NewWorld()
  CaptureToWorld Id

  For lp=0 To 10
     Line 100,100+(lp*5),200,200+(lp*10)
  Next

; Hide element 5 in this world
  WorldElementVisible id,5,off

; restore drawing to immediate mode
  DrawGFXImmediate

; display the number of elements
  Print GetWorldElements(1)

; display the Visible status of the element
; in this world
  For lp=0 To GetWorldElements(1)
