Ok I have find the question 1 answer:

BMAP panneau = "Global01\\panneau.pcx";
...
bmap = panneau;

When you do this, this work!

But I add a question:

4. Why when I open a script wdl just with a double click in my folder a message say "C:\Document not found.".

5. Why when I try to open the panel editor my script editor crash with a startup error E355?
