FindAndReplaceChar
The function finds a character, which may occur more than once, in a string and replaces it with another character.
The function returns
- the number of replaced characters.
- the value 0 if the character was not found.
The function stops the checking of the input length after Parameterlist.cMaxCharacters
characters in order to avoid an infinite loop.
