Checking variables contents
As an exercise on peeking into the contents of variables we will use the seven
variables entered in the exercise above. We showed how to use the FILES

Next, type these keystrokes: @@A12@ ` @@@ª@@ ` L @@@A@@@ `. At this point,
the screen looks as follows:
Pressing the soft menu key corresponding to p1 will provide an error message
(try L
