The biggest benefit would be NO MORE CODING STANDARDS! Yippee, no more whining about this coding standard verse that one. You just set any coding standard you want in your editor and nobody will ever care. And many great advantages for doing code refactoring as well. A more realistic way would be to store source code in XML format, which then could be read into either a xref and symbol database or into a compiler (or into an editor of course). But when you try to deal with file based languages, Java is bad for this (path = package name), as is C due to the use of static, you start to have some problems. Ian. "Timothy M.
