Thanks for the reply to my original question.
Another question I have is related to switching from one file to another. For example, if I have just finished with one file on a floppy, how do I exit that file and get back to the original catalog for that floppy? I try <esc> and <reset>, and all combinations of <ctrl>, etc. But nothing happens. Specificlly, I was playing an old technology "pac man" game. When the game was over, all I could do was go back to begin the game again. There was no reponse to any of the keystrokes I tried, except to reset and start the game again. The only way I can get to another file is to turn off the machine and reboot.
