Frank,

This is confusing worksheet functions with VB/VBA functions. Functions can
change the attributes of the container application (such as worksheet cell
attributes) if they are not called from a worksheet function, just like a
sub.

Hi Rob
one difference between sub and functions:
Function can not change the Excel environment. That is they can't
change formats, other cells, etc. Only subs can do this.

Also have a look at http://www.cpearson.com/excel/differen.htm

Why do we use a Sub instead of using a Function?

Is there any reason other than a Sub returns nothing?

These both do exactly the same thing:

Function Test()
MsgBox "test"
End Function

Sub Test()
MsgBox "test"
End Sub

At the moment my opinion is that Sub is redundant and may as well
never be used.

Thoughts? Comments?
