INSERT2

The function inserts a string into another string after position nPos. If nPos = 0, the string is inserted before the first character of the other string.

The function returns

TRUE if the string was successfully inserted.
FALSE if the resulting string is longer than the output string and doesn't fit in the given output buffer. The memory requirement for the resulting string is then larger than that for the output string. The string is then truncated.

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