That is why I asked the question.  I've seen Ethan's histogram demos, loo=
ked at the script, but total understand if it does the binning and now th=
at 'histeps' comment is obsolete.

Anyway, if that prob3.dem I gave can be used, I'd think that doing a hist=
ogram of randomly generated data would be a worthwhile addition.
