Hi,
Unprotect[Set];
Set[Part[s_Symbol, i_Integer], rep_String] :=
Module[{ch}, ch = Characters[s];
ch[[i]] = rep;
s = StringJoin @@ ch] /; Head[s] === String

Protect[Set]

message = "Hello";

message[[2]] = "bo"

"Hbollo"

Regards

  Jens

| Hello,
|
| In the C programming language I can operate 
directly over the
| characters of a string, like:
|
| int main() {
|
| char message[16] = "Hello!";
| message[n]='a';
|
| /* ... other code ... */
| return(0);
|
| }
|
| This mean: Change the (n+1)th character (in C, 
array starts at 0) to the
| specified character.
|
| Q: How can I obtain similar effect in 
Mathematica?
|
| Thanks!
