Thanks for the info.

I won't be needing WConio, because I don't use windows.

However, I have been tinkering with curses (I use Linux exclusively) and
have found it frustrating. It looks like what I need, but I can't find much
by way of examples on line, as to how to use it.

for instance, when run from a file, this generates an attribute error:

import curses

stdscr = curses.initscr()

stdscr.addstr(0, 0, "Current mode: Typing mode", curses.A_REVERSE) 

_____________

Now that is exactly from the python docs. It croaks on line 3,

stdscr = curses.initscr()

but according to the docs, that initialization should work. Geeze, what
I want to do is so simple, I want to be able to position the cursor and
maybe use some color, in a text application. It shouldn't be this hard.
I had less trouble using NNTPlib.

Cheers,

Mathew
