Calling Sequence

---

      rtics, a1, a2, da, r1, r2, [rl, lb, sz, flg]

Inputs

---

      a1, a2, da = tic mark start angle, end angle, step in
          (deg CCW from X axis).
      r1, r2 = start and end radii of tic marks. in
      rl = label radius. in
      lb = string array of labels. in
      sz = Text size. in
      flg = label angle flag. in
            0: read from outside circle (def),
            1: read labels from inside circle.
