Spursucher as quadrature encoder with fast counter (ZE)

As part of my somewhat longer project of adding an LCD to the Robo Interface and combining C and RoboPro, I found a way of using the fast counter in the Robo Interface escpecially for use with encoder motors like the Maxon. I don't have such a motor so I used a Spursucher to achieve a similar result.
