-===== Poly (Statement) =====
-==== Format ====
-**poly** [[arrays|variable[]]]\\
-**poly** ( [[arrays|variable[]]] )\\
-**poly** [[Lists|{ x1, y1, x2, y2, x3, y3 ... }]]\\
-**poly** [[Lists|{ {x1, y1}, {x2, y2}, {x3, y3} ... }]]
-==== Description ====
-Draws a polygon.  The sides of the polygon are defined by the values stored in the array, which should be stored as x,y pairs, sequentially. The length of a one dimensional array/2 or the number of rows on a two dimensional array will define the number of points.
-One dimensional arrays and lists must have at least six values and an even number of values.  A two dimensional array may have 3 or more rows but must have two columns.
-==== Example ====
-<code>
-# using an array
-clg blue
-color green
-dim tri = {100, 100, 200, 200, 100, 200}
-poly tri[]
-</code>
-<code>
-# using a list
-clg blue
-color green
-poly {{100, 100}, {200, 200}, {100, 200}}
-</code>
-Both programs use the poly statement to draw the following:\\
