What is "very simple"? The problem or the solution? :) If you examine
this suggestion more closely you will note that it is more or less
the same as Benji York's one except Benji used a built-in class.

If you are interested in getting help on usenet you should abstain
from devaluating efforts to give you a useful reply. "Thanks for
the suggestion" or even no answer would have been sufficient.
