excel application

[Petr Jakes]

Luca,
you can find a lot of answers to your questions on this discussion
group. If you will try to search using key words "excel constants" for
example, you will get the link to the following link (among others):

IMHO it is good idea to search the web and discussion groups before
posting questions (I am not saying it is a bad idea to ask here, I am
only trying to show an simple alternative how to get an answers to your
questions to you)

HTH
