Remarks

 

If Length is omitted, or there are fewer than length characters to the right of the Start character of StringExpression, all remaining characters of StringExpression, including the Start character, are returned.

If Start is negative, the starting position is assumed to be Start characters from the end of the string.

If Start evaluates to a position outside of the string on either side, or if Start is zero, an empty string is returned.

If Length is negative, all characters from start position to the end of the string are returned.
