Doubtful. Do you want to do this at the grammar level, or the file level? If you want it at the file level, you C<tie> a translator (ooh! my first p6 idiom!) to the file handle. If you want it at the grammar level (i.e., regardless of source, preprocess it for me) you want to have a composition mechanism. I can see coding tr(1) as a translator (duh!) but I think your C parser is always going to want the preprocessor attached. Finally! TRIMTOWTDI! (RI=really is) =Austin
