+|X, Y, Amt(0-1)| |''x1 y1 b1 -- ''|
+=== Description ===
+Sets wall values at specified coordinates.
+The amount must be in the range of 0 to 1 where 0 means no wall, and 1 means a full health wall.
+=== Examples ===
+Create a rectangle of permanent walls that can't ever be destroyed by Creeper, by repairing them every 9 seconds.
+This example will create a square of walls, with the first corner being at X1,Y1(32,32) and the second corner at X2,Y2(64, 64). As these values are [[crpl:docs:define|Input Variables]], you can change them in the editor.
+<code>
+$wallX1:32
+$wallY1:32
+$wallX2:64
+$wallY2:64
+GetTimer0 eq0 if
+SetTimer0

+			I J 1 SetWall
+		loop
+	loop
+endif
+</code>
+Spawn walls under this unit based on its cell width and cell height. Repair these walls every 9 seconds, effectively making them Crazonium (invincible) walls.
