You could also output the text, and give it to 'less' to display it. This is exactly what 'man' does. You start other programs from python with the 'subprocess' module: http://docs.python.org/library/subprocess.html You could also go the classical Unix way and output the text to standard output (just use print). If necessary you could then give the output to 'less'. Your program(s) would be used in the following fashion: my_program --foo -a -b -c --be-cool --read this-file.txt | less Command line options are parsed with the 'optparse' module: http://docs.python.org/library/optparse.html Kind regards, Eike. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
