The -ansi option switches off any extensions that conflict with the standard. It also enables trigraphs, a standard "feature" almost no-one ever uses. Your chances of writing portable code do increase if you can get it working with more than one compiler from the start though. And error messages and warnings from multiple compilers are often more enlightening than from just one. HTH Simon Bone
