This is a simple typewriter program, where the user types characters which are then echoed to the screen. The typerwriter is a variant of the custom input routine found on the intro screen, where keypresses are captured with GET. There are several limitations to this program: the INST (INSerT) key does not function, you cannot scroll past the bottom of the screen, and there is no way to save your typewritten screens.
All of the credited programs on this tape were written by Glen Fisher.
