Obviously, the code I provided last time doesn't perform any error checking. I will leave it as an exercise for the reader if any of these are important in the strings you'll be processing.
the numbered text files are written by the GTK+ and the user who is typing and creating the files. the files are then read by the computer to others.
so the numbers, dots, and "text" ending are assured.

what i realized a few weeks ago was that i needed a Fourth button in case one of the users' sentences need to be repeated.
