PLTSQ

       SUBROUTINE  PLTSQ
 C$    (Square Bordered Frame)
 C$    Set up  a  rectangular standard  paper  size frame  with  a
 C$    square inner frame  centered inside  of it,  and reset  the
 C$    unit square to  correspond to the  inner frame.  The  inner
 C$    frame is  usually desirable  for  contour plots,  since  it
 C$    prevents contour  lines from  appearing to  be "hanging  in
 C$    air".  Use of  this routine instead  of PLTBO ensures  that
 C$    uniform scaling in  X and Y  is maintained.  The  narrowest
 C$    margins around the  square frame  are set at  0.075 of  the
 C$    page width,  using 85  percent of  the width  for the  plot
 C$    frame.
