DESCRIPTION

     The following  commands provide various  graphical device
     routines   and  filters.    They   all   reside  in   the
     /usr/bin/graf directory (see "graphics").

       hpd

     The  hpd command  takes a  graphical file  in gps  format
     (standard  input  by  default), and  translates  it  into
     instructions  for  the   Hewlett-Packard  7221A  Graphics
     Plotter.  See the gps file  in AIX Operating System Tech-
     nical Reference  for a  description of this  file format.
     It computes a viewing window from the maximum and minimum
     points  in the  file, unless  you  specify the  -r or  -u
     flags.

     FLAGS

     cnum   Selects character set num, where num is an integer
            between 0  and 5.   See  the Hewlett-Packard 7221A
            Graphics Plotter documentation for a list of these
            character sets.
     pnum   Selects pen numbered num,  where num is an integer
            between 1 and 4 inclusive.
     rnum   Displays a window on a GPS region, where num is an
            integer from 1 to 25 inclusive.
     snum   Slants characters  num degrees clockwise  from the
            vertical.
     u      Displays window on the entire GPS universe.
     xdnum  Sets x  displacement of the viewport's  lower left
            corner to num inches.
     xvnum  Sets width of viewport to num inches.
     ydnum  Sets y displacement of the viewport to num inches.
     yvnum  Sets height of viewport to num inches.

       erase

     The erase  command sends  characters to a  Tektronix 4010
     series storage terminal to erase the screen.

       hardcopy

     When issued at  a Tektronix display terminal  with a hard
     copy unit, the hardcopy command produces a screen copy on
     the unit.

       tekset

     The tekset  command send  characters to a  Tektronix ter-
     minal to clear  the display screen, set  the display mode
     to alpha, and set characters to the smallest font.

       td

     The td command translates a  GPS object to scope code for
     a Tektronix 4010 series  storage terminal.  It computes a
     viewing  window from  the maximum  and minimum  points in
     file, unless you specify the  -u or -rnum flag.  Standard
     input is the default input file.

     FLAGS

     e    Does not erase the screen before initiating display.
     rnum Displays  GPS region  num, where  num is  an integer
          between 1 and 25 inclusive.
     u    Displays the entire GPS universe.
