Apparently it does.  Just to wrap up this thread and hopefully help the next
person.  When SELECTing multiple values into variables only use one instance of
the INTO clause.  i.e.

SELECT col_a,
       col_b,
       col_c
  INTO var1,
       var2,
       var3
  FROM foo
 WHERE fobar;

Kind Regards,
