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

  The CLOSE DEVICE statement allows you to explicitly  close  a  specified
  device.   Subsequent  graphics  output  will  not  be  displayed on this
  device.  If all devices are closed and graphics  output  statements  are
  executed, VAX BASIC opens the default device.

  Example

  OPEN "VTA247" FOR GRAPHICS AS DEVICE #2
  OPEN "my_term" FOR GRAPHICS AS DEVICE #3
  !+
  !Display metafile on devices #2, and #3
  !-
  GRAPH METAFILE "states_outline.pic"
  !
  !Close device #2
  !
  CLOSE DEVICE #2
