NAME
     wshore - Draw coast, lake and rivers with small scale
     rshore - Define the range to draw coastlines etc. by 'pshore'
     pshore - Draw coast, lake, rivers, prefecture boundary with larger scale

SYNOPSIS

      call rshore(m, is, in, kw, ke)
      call rshore(is, in, kw, ke)
  m           [int]   Specify whether old Tokyo Datum (m¡á0) or WGS (m¡á1) to
                      use as a reference geodetic system.
                      Must be m=0 or m=1. Otherwise, the calling is treated as
                      the second form with 4 arguments, where old Tokyo Datum
                      (m¡á0) is assumed.
  is, in      [int]   Specify latitude range to draw.
                      Must be 20 <= is < in <= 50 .
  kw, ke      [int]   Specify longitude range to draw.
                      Must be 120 <= kw < ke <= 155 .

      external conv
      call wshore(xorg, yorg, mpen, scl, conv)
      call pshore(xorg, yorg, mpen, scl, conv)
  xorg, yorg  [float] Coordinates (in cm) of the origin in the drawing.
  mpen        [int]   Specify pen numbers to draw coast / lakes and rivers /
                      prefecture boundary in the form of 3 digits number:
                      pen numbers for prefecture boundary / lakes and rivers /
                      coast on the digits of 100 / 10 / 1 , respevtively.
                      As a special case, if mpen=99, the coast of world is
                      drawn by current pen.
  scl         [float] Reduction rate.  Coordinate values of scl given by 'conv'
                      is represented by 1 cm of length on the drawing.
                      (If the coordinate values are in km, the drawing scale is
                       1 : (scl*100,000) .)
  conv    [ext.symb.] External procedure name to define projection, i.e.,
                      the name of subroutine with 4 arguments as follows:
                         subroutine conv(alat, alon, xe, yn)
                      where Lat. (alat) and Lon. (alon) is converted into
                      drawing coordinates toward right (xe) and upward (yn) .
