  fieldname
  (optional)          Specify  fieldname(s)  of  the  graphic  attribute  to  be

                     The  possible  fieldnames  are  xvisiblesize  (visible  x
                     dimension screen area in pixels), yvisiblesize (visible y
                     dimension  screen  area  in  pixels),  nplanes  (number of
                     planes available), and nprimaries (number of primaries for
                     graphics, either 1 for monochrome or 3 for RGB color).


OPTIONS

  Default options are indicated by "(D)."

  -X           (D)   Specifically give value of x visible screen size.

  -Y           (D)   Specifically give value of y visible screen size.

  -P           (D)   Specifically give value of the number of planes.
