I downloaded TCl 8.69 and have been playing with it. They give you TCL example files to run. One interesting file was about 1.5 meg. When I ran it, it would always ask for msg 1.6 (whatever that is) so I tried to edit the file to remove the part that made the error. The Freedos editor said it was too big so I used wordperfect to do it, which had zero problems doing it. Still got the message with that part removed. Tried TCL 8.5 also; its examples run wiithout the error but 8.5 doesn't have any of the TK commands like buttons.
