  Mike:

  When you run WIRE.EX in LINUX the draw_line procedure is trying
  to use FLOATING POINT NUMBERS for coordinates.

  For some reason ( which Rob might know ) the M_LINE machine procedure
  seems converts them internally to integers.

  A temporary fix until you figure out what is wrong is to use floor
  on each coordinate like the following in the draw_line procedure.


--      vga_drawline(xyarray[ctr-1][1],xyarray[ctr-1][2],xyarray[ctr][1],
--  xyarray[ctr][2])

       vga_drawline(floor(xyarray[ctr-1][1]),floor(xyarray[ctr-1][2]),
                    floor(xyarray[ctr][1]),  floor(xyarray[ctr][2]))

   This will allow WIRE.EX to run in LINUX, but I don't know if the
   other demos will have other problems.
