The process Linus described is also available in EG 3.x .
However, that is not how I read the question. I heard a need for near real-time data transformation (change the value in the data, hit tab, and the new value pops into another field). EGuide is not designed to do that. It is a client-server architecture (even if EG and the SAS server are both local), so those sorts of data transformations are not supported. You can set up parameters so that the changed values are requested at run-time, but it's not the same as being able to make the same style of data manipulation that you can in Excel.
