[(ring_of_differential_difference_operators)

[ ([string1 string2] ring_of_differential_difference operators)

(This command is used to define a ring of differential-difference operators )

(with the macros define_ring, weight_vector and elimination_order.)

(string1 is a set of variables for differential operators.)

(string2 is a set of variables for difference operators.)

(The user cannot use the variable names h, e, H and E.)
