We have a dos application that was recompiled to run in Windows.  It looks
like a dos application running in a window (a dos-box), but it runs in
Windows and you can call Windows API from it.  The users want to be able to
copy the app screen and paste into documents as text (not a bitmap image) as
you are able to do with a real dos app.  Basically, they are asking for the
"Edit - Mark - Copy" functionality you find in a dos-box's system menu.  How
should I go about doing this?  Where do I start?

Thanks,
