Unreadable Code

code in examples unreadable and full of magic. It is not clear, what it is doing.
For example:

    ;Anchor by Titan, adapted by TheGood
    ;http://www.autohotkey.com/forum/viewtopic.php?p=377395#377395
    Anchor(i, a = "", r = false) {
        static c, cs = 12, cx = 255, cl = 0, g, gs = 8, gl = 0, gpi, gw, gh, z = 0, k = 0xffff, ptr

May be add more of simpler exaples?
