return                       return Statement

 return [expression];

    The return statement is used  to terminate a user-defined function  and
    return  control  to  the  statement  following  the  call.   The return
    statement may also be used to return a value.

      Notes:    If no value is returned, the return value is undefined.

                Although it is a  bad programming practice, it  is possible
                to return from multiple  places in a function,  returning a
                value from some points, but not from others.  This is  sure
                to bite you at some later time, and should be avoided.

                The return expression is  often written as return  (value);
                The  parentheses  aren't  necessary,  but  they  don't hurt
                anything.

               return;                # Return value undefined


           if ( condition )
               return i;              # Value of i is returned


           if ( condition )
               return ( i );          # As above; value of i is returned
