Please include setring D1; after you defined D1. |

Thanks! It works in a terminal, but still does NOT work in a Sage worksheet. This is a problem for the Sage team. J. W. Hoffman |

Hi, GKZid calles subprograms for integer programming through toric.lib. Toric.lib in turn calles special, separatedly compiled binary routines, which have to be present in the same directory where Singular binary resides. These are solve_IP, toric_ideal and so on. Possible SAGE guys do not compile them [yet]. I am open to more questions on the computational D-module theory. Regards, Viktor |
