Indexing into a string

[webmasterpdx]

I'm currently working with strings and something very inconsistent is going on.
Lets say I have a string, s, that is something like "This is a very nice day".

However, when I use s(3), it returns a number instead of "i".
I have to use CHAR(s(3)) to get the character.
Surely an index into a string should return a string.
Is there a faster way to index into a string to return a string? Anyone know?
Thanks

I also discovered an at() and of() functions that seem to have something to do with strings, but for which there is no documentation. Can these be of use?

I think I've got it!
It's s(3,1) gets 1 character from s at position 3....returns "e" if s contains "The dog".

The zero'th list index is also useful. It points to the tail of a list, where the last element can be returned, deleted, or a new element appended to the list.

Example:
L1:={4,9,16}; L1(0):=√(L1);

at(M,I) is a function to index a matrix or string, etc.. or M[I].
of(f,x) is the same as f(x).
