The teachpack provides three functions:

procedure
(control index) → symbol?
index : natural-number?

reads out the indexth guess choice, starting with 0

procedure
(view msg) → true/c
msg : (or/c string? symbol?)

displays its msg argument in the message panel

procedure
(connect event-handler) → true/c
event-handler : (-> button% event% true/c)

connects a controller (handler) with the Check button displays frame

Example:

(connect
(lambda (e b)
(view (control))))

This example simply mirrors what the user types in to the message field.
