cDEC$ ATTRIBUTES

  Lets you specify properties for data objects and procedures.  It
  takes the following form:

  cDEC$ ATTRIBUTES att [,att]... :: object [,object]...

    c        Is one of the following: C (or c), !, or *.

    att      Is one of the following properties:

             ADDRESS64
             ALIAS                        EXTERN
             ALLOW_NULL                   IGNORE_LOC
                                          NO_ARG_CHECK
             C                            NOMIXED_STR_LEN_ARG
             DECORATE                     REFERENCE
             DEFAULT                      REFERENCE32
             DESCRIPTOR                   REFERENCE64
             DESCRIPTOR32                 STDCALL
             DESCRIPTOR64                 VALUE
                                          VARYING

    object   Is the name of a data object or procedure.

  The properties can be used in function and subroutine definitions,
  in type declarations, and with the INTERFACE and ENTRY statements.

  Properties applied to entities available through use or host
  association are in effect during the association.  For example,
  consider the following:

  MODULE MOD1
    INTERFACE
      SUBROUTINE SUB1
      !DEC$ ATTRIBUTES C, ALIAS:'othername' :: NEW_SUB
      END SUBROUTINE
    END INTERFACE
    CONTAINS
      SUBROUTINE SUB2
      CALL NEW_SUB
      END SUBROUTINE
  END MODULE

  In this case, the call to NEW_SUB within SUB2 uses the C and ALIAS
  properties specified in the interface block.

  Options C, STDCALL, REFERENCE, VALUE, and VARYING affect the
  calling conventions of routines:

   o  You can specify C, STDCALL, REFERENCE, and VARYING for an
      entire routine.

   o  You can specify VALUE and REFERENCE for individual arguments.

  For compatibility, !MS$ATTRIBUTES can be used in place of cDEC$
  ATTRIBUTES.

  The properties are described in the following sections.
