Five user interfaces are available: a Shell interface (Pips), a line interface (Tpips user manual and tpips man) and three window-based interfaces. The three X-window interfaces Wpips, Epips and Jpips to the workbench are the best suited for new users (see the wpips man and WPips and EPips user manual). The last interface is Java based but not yet available. Click here for a Wpips screen snapshot.
Unfortunately, right now there is only tpips (prefered way to use PIPS) and the shell interfce that are still working, because of various library deprecations. There are also some other interfaces in Par4All.
