Yes it does. I had to think real hard about it. With a[0][0] I expected 
to get a value from a matrix (but there is no matrix, give me the blue 
pill please), when I'm actually calling a method from a string. Why it 
returns 97 is beyond me at this moment, but it's not relevant. Duck 
typing fooled me, I guess.

Regards and thank you,
