Subject: Neewby question: how to monitor a variable value

Hello All,

I remember reading in a book that we could very easily monitor the
value of a variable and have for instance an alert message displayed
each time this variable s modified. I do not manage to find how to do
this anymore.
Would you have any clues ?

Thanks a lot,
Luc
