DELETE2

The function removes nLen characters from a string, starting at position nPos.

The function returns

TRUE if the characters were successfully removed.
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.
