But I fail to see the logic behind considering "aa" but not "aaa" in the evaluation. But then again, I'm not that informed. > > Enough said. NOOOOO! More must be said!! a <= z b <= z c <= z ... y <= z z <= z aa <= z ab <= z ac <= z ... az <= z ba <= z bb <= z bc <= z ... cz <= z ... dz <= z ... ... ... yx <= z yy <= z yz <= z za > z SOOOOOOOOOOOOOOOOooooooooooo, the comparisons stop before we get to aaa and so aaa is never reached. za is the last comparison to occur at which point the test fails and the loop stops.
