LOGO-L> is there an "undo" in Logo

I have been teaching (and learning) my 7 yeqr old Logo.
After fooling around drawing squares , triangles, rectangles etc we
got into a structured mode of doing all the alphabets. he really got
interested and motivated in doing the alphabets. In the process of
doing by trial and error, what we figured we need is an "undo' command.
After turning and moving, if the result is not what's expected he would
like to erase and start over ( the last 2 commands).

It was a real pleasure watching him discover the concept of subroutine-
Hey I can use the 'V" to do "Y".He calls it packaging. He explained his
mom that all the commands go between "to something" and "end" and get
neatly packaged and he can use it (package) again.

I am using MSWLogo (for windows). I am not a teacher but a professional
programmer.

Any suggestions, to keep us going ?

Thanks,
Balu Raman
