Quote discoleo: I do not quite understand this statement. In general named
ranges should be preferred...

I agree, and I use them.
But, suppose you defined variable AB6 for some formula, 3 months ago.
Now, you reopen the same spreadsheet to add some some other calculation using
cells AB6 and AB7, say '=AB6+AB7'. (Even if you 'strongly prefer' named ranges,
you likely use also direct cell references, for their simplicity.) IF you are
very careful, you will first hit ^f3 to check if AB6 or AB7 has already been
defined as a variable.
   However, the average user will not even think of doing such a check, and
believe he has added cells AB6 and AB7, when in fact he has added VARIABLE AB6
to cell AB7, without error message since the operation is legal --but not what
was intended!
   'Friendly' software should --within reason-- protect the 'careless' user
against likely mistakes. (Toughware will tell the user: 'Haha! You should have
known that AB6 is a variable name!') Forbidding variable names that would
duplicate cell names is an simple way to avoid the above problem, and this
restriction is very easy to satisfy: if the name 'AB6' is not a legal variable
name, 'AB_6' is, as are 'AB6v', 'AB6_', ....
