I am almost sure that you can increase the value of b in other part different than in the 3rd param of the loop

;b++)

perhaps the last b used inside the loop?

I noted you did this in another entry on 140bytes, you might want to recheck them, search for "for(" inside here http://www.140byt.es/users/jed
