I think I appreciate what you are trying to do here. I don't intend to sound negative here, but if the keyword AUTOMATIC does nothing how difficult is it really to just run a script on all your source code using something like sed and just strip it out. 5 minutes to develop the script, 13 seconds to run it. Or maybe a preprocessor directive that defines AUTOMATIC as '' I must be missing something here. Regards, Jerry
