No, the above title is not incorrect. I have updated the Command list on my website to now list all of the new or changed commands in AutoCAD 2009. It is amazing to see all the commands back to AutoCAD R12 with those that are still in AutoCAD 2009 today and the ones that have been added along the way. As for the System Variables list for AutoCAD, the work is well under way, but will take a little while to complete it as there is more information that is contained in that list than just which system variables are available and in which release. Hope you enjoy the walk through history.
