After assigning the symbol, enter the delimiter "<<<", followed by the identifier, you can use your goddess as the identifier "GOD", such as line 2nd, you can also use your favorite dog, "dog" as an identifier, but at the end of the identifier must be the same. In addition, at the end of a line, such as the 7th line, must be another row, and this line except "GOD", and ";" After the end, there can be no other characters, before and after can not have, including spaces, otherwise it will appear wrong oh.
