Description_File

   The following description file directs MMS to build MYPROG.EXE using
   the appropriate architecture-dependent *_DEFS.REQ:

        ! Macro definitions
        LIBRARYMODULES = A, B, C, D, E
        LIBRARIES = MYPROG.OLB($(LIBRARYMODULES)) - ! project library
                    SYS$LIBRARY:CRTLIB.OLB          ! C Runtime Library
        ! Dependencies
        MYPROG.EXE : $(LIBRARIES)
             LINK/EXEC=MYPROG MYPROG/LIB/INCLUDE=(A)
        .IF MMSIA64
        A.OBJ, B.OBJ : IA64_DEFS.REQ
        .ELSIF MMSALPHA
        A.OBJ, B.OBJ : ALPHA_DEFS.REQ
        .ELSE
        A.OBJ, B.OBJ : VAX_DEFS.REQ
        .ENDIF
        D.OBJ, E.OBJ : COMMON.H
        E.OBJ : DATA.H
