Sad thing is, I doubt they really know. They aren't allowed to do anything to the code per orders from the parent company in Germany. They're basically support for US issues that funnel back to Deutschland. One of my first co-op terms there I was looking through a bunch of lines of code, and it's pretty interesting. It's all block diagrammed and C-code generated from it, like Simulink in Matlab. I'll still ask, but if I get an answer, take it with a grain of salt.
