This tutorial covered only a small subset of the commands in OneLiner. You can find a detailed description of all the commands in Section 3 of the on-line help. You may also read Section 4 to see how OneLiner models the various network elements. Finally, you may wish to browse through the appendices, which cover a wide range of topics that include the solution method and techniques for transformer modeling.
You can find tutorials for the ASPEN Overcurrent Curve Editor and the ASPEN Distance Relay Editor in Section 2 of the respective User's Manual. (Not included in the Working Model.)
