FindAndDeleteChar
The function finds a character, which may occur more than once, in a string and removes it.
The function returns:
- The number of removed 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.
