FIND2
The function finds a string, which may occur more than once, in another string.
The function returns:
- The position of the first character of the first string found.
- 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.
