From Ada.Text_IO? No you cannot, File_Type is not tagged. For a stream you could. > I know there are versions of Put that take a string as a first argument but I don't want to have to write a special-purpose version of a stretch of code just for this purpose, since I want to keep the ability to also output text to a terminal. I would say that one should never use anything but Put_Line and never instantiate any I/O packages. First format an output line in a string, and then output the string. I would suggest to define logging/tracing package, instead of doing direct output. It always pays off. -- Regards, Dmitry A. Kazakov http://www.dmitry-kazakov.de
