Hi, stumbled upon interesting project http://idlex.sourceforge.net/ It has line numbers! which is very nice for beginners looking for errors... and more... ps.: could IDLE editor be easily implemented in python-turtle-demo code frame? As I have simple step/by step and breakpoints/watches implemented in python-turtle-demo, but editor is not functional there... -- Jurgis Pralgauskis tel: 8-616 77613; Don't worry, be happy and make things better ;) http://galvosukykla.lt
