Counting a string

[Benedikt Müller]

Hi
I want to =E2=80=9Ecount=E2=80=9C a string. I don't know, how to express it=
better,
because of that I'll try to explain it. I have a string, say 'a'. Now
I want to increase it, so it would be 'b'. I increase it again, it
would be 'c' and so on.
Is there a method for this task?

I want to „count“ a string. I don't know, how to express it better,

would be 'c' and so on.

Try:

"a".succ
=> "b"

thx
Sorry I looked in ruby-doc in the String class but I didn't saw it so
I thought that isn't in the standard lib.

Is there a possibility to say what chars can be in the string? I want
to have upper chars and lower chars but i want to start with only one
char.
