The code below is typical of code used in a particular vendor's gauges. The primary purpose of the code is to toggle the AdfOn variable, but what's the purpose of the afterburner reference, when the plane has no afterburners? Are they using it as some sort of temp?0 (>K:TOGGLE_AFTERBURNER2) (L:AdfOn,bool) ! (>L:AdfOn,bool)Thanks,Dave

The use of (>K:TOGGLE_AFTERBURNER2) was used as a part of a XMLsound gauge by the late Bill Morad. It was a workaround to provide sounds for gauge "clicks", "toggles", "thumps" etc... using this older version doesnot work in FS9 unless the aircraft is a jet, where in FS2002 the (>K:TOGGLE_AFTERBURNER2) works because that version allowed the coommand even if it was a recip prop aircraft. There is a new and very well implemented sound gauge by Doug Dawson here in the library, but in order to use the code for al the gauges in your panel will have to be rewriiten to use.Regards,Roman(KGRB)

Thanks for the info. I figured it had to be some funky hidden thing. :)
