This probably is a very dumb answer, as I do not even have a Prime at hand to check it. But in all programming languages I know the "replace" string function does not replace the i–th character, instead it replaces one substring by another. Like this:

replace("apple pie", "apple", "orange") => "orange pie"

So the right approach may be something like a simple replace(x," ","9"). No for-loop required.

But again: probably this is a very stupid answer. You should know since you've got the manual. ;-)

I tried this:

PHP Code:

x:="apple pie";
replace(x, "apple", "orange");
print(x); 


"apple pie" prints. I'm really craving orange pie! It seems to be a problem replacing characters in a variable.
