[en] The impurity transport code 'Strahl', already providing some rudimentary neoclassical transport facilities, has been described in a previous report. The code has been amended to include different collisionality regimes of impurity and plasma ions, and to allow a second impurity species to be specified and included in the transport calculations. More input parameters have been defined, which were necessary for the more detailed transport coefficients, but also give greater flexibility in the modelling of actual plasma pulses. Finally, the possibility of following the evolution of plasma parameters by means of a sequence of code re-entries has been facilitated, and a number of minor changes were made, which were thought to be necessary or convenient. The present report gives an account of the equations used in the above amendments, and of the ideas behind other changes made. New listings of the code 'STRAHL' and relevant subroutines are appended. Furthermore, a brief description and a listing of the program 'NEPLO' are included, an indispensable prerequisite for displaying all input parameters to 'STRAHL', which is using the same subroutines for calculating transport coefficients, as well as atomic data and radiation.
