Hello world,

I'd like to have an Excel 2003 VBA macro be automatically called each time
that the user changes the value of a cell (by either directly entering a new
value of using copy/paste).

* How can I make my macro be automatically called in such a case?
* How can I detect which cells was changed from inside the macro?

My macro should check the new cell value and change it under certain
conditions. In case the cell value is changed by my macro, is there a way to
prevent the macro from being called again for the same cell?
