The following module definition:

MODULE YOMCAIN

SAVE

TYPE distributed_vector
REAL, pointer :: local(:)
INTEGER       :: global_length,local_start,local_end,nchnks
END TYPE distributed_vector

INTERFACE ASSIGNMENT (=)
MODULE PROCEDURE assign_dv_dv
END INTERFACE

INTERFACE OPERATOR (*)
MODULE PROCEDURE multiply_dv_dv
END INTERFACE

CONTAINS

SUBROUTINE assign_dv_dv (handle1,handle2)

TYPE (distributed_vector), INTENT(IN)    :: handle2

RETURN
END SUBROUTINE assign_dv_dv
