                     24: The program will ask questions to find out what

                     26: The questions may be bypassed by naming a

                     37: .I learn

                     71: .SH BUGS
                     72: The main strength of
                     73: .I learn,
                     74: that it asks the student to use the real
                     75: UNIX, also makes possible baffling mistakes.
                     76: It is helpful, especially for nonprogrammers,
                     77: to have a UNIX initiate near at hand during the first
                     78: sessions.
                     79: .PP
                     80: Occasionally lessons are incorrect, sometimes because the local version
                     81: of a command operates in a non-standard way.
                     82: Such lessons may be skipped,
                     83: but it takes some sophistication to recognize
                     84: the situation.
