       abstract = "The software system PCOMP uses automatic differentiation to calculate derivatives
         of functions that are defined by the user in a modeling language similar to Fortran. This symbolical
         representation is converted into an intermediate code, which can be interpreted to calculate
         function and derivative values at run-time within machine accuracy. Furthermore, it is possible to
         generate Fortran code for function and gradient evaluation, which has to be compiled and linked
         separately. The first version of PCOMP was introduced in Dobmann et al. [1995]. In this article, we
         describe a series of extensions and additional features that have been implemented in the
         meantime.",
