Hi guys.

I try to name a range by putting name "S1Mod" there.
It gives me a message that range name is invalid.

The same happens when I try execute

ActiveCell.Name = "S1Mod"

It is an error in German version of Excel and in multi language version
when language is set to German.
It works fine with other version of Excel and with other languages.
Excel 2003.

What is a rule?
S1xxxxx in not valid.
K1xxxxxx is valid.
