RETURN

 Transfers control from a subprogram to the calling program.  You
 can only use RETURN in a subprogram unit.  Statement format:

    RETURN [i]

    i  Is an optional integer constant or expression (such
       as 2 or I+J) indicating the position of an alternate 
       return from the subprogram in the actual argument list.
       The "i" is converted to an integer value if necessary.      

 The argument "i" is valid only for subroutine subprograms.  If no
 alternate return is specified or the specified alternate return
 does not exist in the actual argument list, control returns to the
 statement following the CALL statement.


                                NOTE

         An alternate return is an  obsolescent  feature  in
         Fortran  95  and  Fortran 90.  VSI Fortran fully
         supports this feature.


 If the subprogram is a function, control returns to the statement
 containing the function reference.  If the subprogram is a
 subroutine, control returns either to the statement following the
 CALL statement, or to the label specified by the alternate return
 argument.
