Does anyone know how to:

  1) Create a window from a 'C' program that can NOT be resized
     by the user? I have a window that must be a fixed size, but
     currently the user can "grow" it and things get messed up.

  2) Create a window whose size includes the legend and border?
     It seems that when I use:

       window.left   = 100;
       window.top    = 100;
       window.width  = 100;
       window.height = 100;
       pad_$create_window("", (unsigned short) 0, pad_$transcript,
         window_no, window, ios_id, status);

     the window specified is really the interior of the window. The
     exterior of the window that I get is l=96, t=76,b=204,r=204.
     These numbers are different on different machines. I think that
     is because the size of the fonts used on those machines is
     different, so the legend changes size.

  3) Access the node id with a 'C' procedure?
     The closest I found was in /usr/include/apollo/osinfo.h
     osinfo_$node_type which seems to give the model and
     number of cpus.

  4) Place cursor on a named window using the Display Manager (DM)?

  5) Determine the contents of the DM search buffer, preferably using
     DM commands.  Or, how about from a shell script.

  6) Query (all DM) windows info from 'C' program?

  7) Get a the name of the process a 'C' program or shell script is
     running in from that program or shell script?

  8) Use the DM mark stack to do anything useful?  i.e. How in heck
     does that #!&$% mark stack work?

  9) Get the parameters (baseline, line height, etc) for a fixed pitch font?
     The method I use now is show below. It seems to work for f5x9 but not for
     f9x15.

    static gpr_$string_t text = "A";
    gpr_$offset_t size;
    gpr_$offset_t start;
    short int pitch;

    gpr_$inq_text_extent(text, (short int) 1, size, status);
    check_status;
    gpr_$move((short int) 0, (short int) 0, status);
    check_status;
    gpr_$inq_text_offset(text, (short int) 1, start, pitch, status);
    check_status;

    font_info.font_size   = size.y_size;
    font_info.pitch       = pitch;
    font_info.leading     = 2;
    font_info.line_height = size.y_size + font_info.leading;
    font_info.margin      = pitch;
    font_info.base_line   = size.y_size - start.y_size;
