FindAndReplace

The function finds a string, which may occur more than once, in another string and replaces it with another string.

The function returns

the number of replaced strings.
the value 0 if the string was not found.

The function stops the checking of the input length after Parameterlist.cMaxCharacters characters in order to avoid an infinite loop.
