Bob,

Thanks for the reply. I appreciate it. So you mean if I am watching cable and want to switch to the Roku rather than running all of the macro steps for the roku that turns everything on, use variables to track that the audio is on, projector is on, etc. and don't bother running that part of the macro?

Today with my 850, If I want to do that, I hit main on the remote, then select Roku as a source and not a macro from my theater page, then I have a macro in the Roku screen called fixRoku and that switches the preamp source to Roku and toggles the hdmi. So three button presses. Seems like the variables could save me one click and the time for the skipped macro steps if I was reusing the main startup macro for each activity. Perhaps I am missing some of the value of the variables (other than for devices without discreet power codes)

Again thanks for your insight!
