+The values are stored as "fixed point" numbers (divide each number by 128 to\r

+following:\r
+\r
+1. set all pixels on the screen to black\r
+\r
+2. for each of the 4000 entries do:\r
+\r
+2.1 x := posx[i] + velx[i]\r
+\r
+2.2 if x (in pixels) is < 0 or > 320 then go to 2.8\r
+\r
+2.3 posx[i] := x\r
+\r
+2.4 y := posy[i] + vely[i]\r
+\r
+2.5 if y (in pixels) is < 0 or > 200 then go to 2.8\r
+\r
+2.6 posy[i] := y\r
+\r
+2.7 draw a white pixel at position (x, y) on the screen\r
+\r
+2.8 continue with the next entry\r
