GRID

        [GREG2\]GRID [Astep [Dstep]] [/ALTERNATE]

    Plots  a grid of meridian and parallels according to the current projec-
    tion and system. Astep is the grid step for meridian in degrees (Default
    15), Dstep for Parallels (Default Astep). If one step is 0, this part of
    the grid is not plotted. If the /ALTERNATE option is present,  the  grid
    will  be a grid in the alternate coordinate system (Equatorial or Galac-
    tic). This does not currently work for projection type AITOFF and RADIO.
