running myfile.SQL from command line SQLPLUS 12c does not exit.

Hiya.  I am running a script saved as L:\MY_SCRIPT.SQL from command line.  

I want the script to execute, then close SQLPLUS.  
I am trying all the suggested code , adding EXIT. QUIT, . (period) to MY_SCRIPT.SQL  and get errors.
Without these statements the script runs successfully but SQLPLUS stays open.

Windows 7
Oracle 12C 1.0.2.0

Below is the command I cam using
C:\ sqlplus MY_SCHEMA/my_password@MY_DATABASE_LINK @L:\MY_SCRIPT.SQL

The script I am running is straight from Oracle documents:
DECLARE
    x   NUMBER := 100;
    BEGIN
        FOR i IN 1..10 LOOP
           IF MOD (i, 2) = 0 THEN    --i is even
             INSERT INTO temp VALUES (i, x, 'i is even');
           ELSE
             INSERT INTO temp VALUES (i, x, 'i is odd');
           END IF;
           x := x + 100;
       END LOOP;
   END;
   .
/


Below is the output including error:
