> What kind of errors? It will break with an error from the library, if the procedure is to slow. The fpc-writeln() works fine but to slow. The gcc-printf() works fine and fast. Do you know a better way to produce a fast formated output in FreePascal. I would use FreePascal and not gcc, but the fpc result is not practical.
