We study the Weyl closure Cl(L) = K(x) βˆ‚ L ∩ D for an operator L of the first Weyl algebra D = K x, βˆ‚ . We give an algorithm to compute Cl(L) and we describe its initial ideal under the order filtration. Our main application is an algorithm for constructing a Jordan-HΓΆlder series for a holonomic D-m
