Hi Massimo,
[quote user="blumax57"]I thought that by adding an entry this was the last[/quote]
the problem is that you expect a behaviour that is not defined. MicroStation tags have not defined order, the tag set is just an unsorted group of tags without defined order. Moreover it's not known what is a process of reading tags from DGN file and transforming the data to VBA environment as an tags array.

If you question is about if it's possible to obtain such sorted list using .GetTags, I think it cannot be done, because Bentley does not define any behaviour related to tags order.
If it's about how to sort it e.g. for display purpose, you have to sort the array yourself. I think VBA does not offer any array sorting functionality, but there are plenty of discussions about this topic. The most of them are about using Excel, but some are about pure VBA code. But in your case the code will be more complex, because you don't need to sort array of string, but array of tags by their names.
With regards,
Jan
