Is there a Short for Reading and Writing a Char in a String?

Hi


If I have a String, and I need to Read and Write Specific Chars in it,
(not to insert or delete any chars, but only to Read and or Edit the Existings chars)
Is there any Short for it?


Right now what I use, is StringMid($String,$i,1), to get the Char in Position i.
To Set a char in postion i, it's even longer in terms of writing..

In most proghramming language, a string can also be treated as an array of chars,
Can it be used similarly in AutoIt too?


Thank you
