Hi Arpad, I believe our decision was to have "N" as the required parameter. It seems that the example had not been updated accordingly.

The example on the last row of the table shows this line: .model s_model S TSTONEFILE=str(tsfile) However, the previous page shows this syntax for .model: .MODEL Smodel_name S N=val TSTONEFILE=filename Notice that the N=val is missing in the example. What does this mean? Is N=val optional, or is the example wrong? I don't see any mention of the N=val being optional, so my take is that the example is wrong, but I am not sure about this. I think this should be fixed. Thanks, Arpad ===================================================
