Abstract: A computer package for the neutron-proton interacting boson model is presented.It used the F-spin symmetric U(5) limit wavefunction as its basis states.Hamiltonian and other operators are written in terms of F-spin tensorial form.In the input,in addition to the hamiltonian forms in terms of neutron and proton bosons indices,F-spin tensorial formalism is also provided.B(M1) and B(E2) can also be calculated in the package.
