Salut Doriano & Fabian,

I attached a (no, two) gambas2 project(s), which does now, all I
expected to find when I started for that.

Finally what I need is a user "named" Interface which comes back to the
caller which is the users project, who had called my component.
First I planed that the component has to be embedded (for the parents
stuff) but now I found out, I can call back, if the called, knows the
Name of the caller (and the method to call).

That gives me and the user a lot of freedom. 

The reason, why EVAL work with intern method only if you give the name
of the owner (ME.Name) is an extra job for Benoît! 

Amicalement
Charlie
