compiling editor.a

hi,

i've got this problem when i invoked "app editor.a", but strangely for 
the standard file provided with amaya8.6 :

_____
[pulau:Amaya/monAmaya/bin] ninou% ./app ../amaya/EDITOR.A
Allowed only in section DEFAULT

***ERR line 1
APPLICATION EDITOR;
             *
Cannot load structure schema
_____

Same problem with HTML.A, but not with XML.A (at least, nothing to see 
on the sshell)
Is it due to the amaya version i'm working on (the latest 8.6, snapshot 
release) ?

Thanks,

Nicolas

NB : i'm in a rush now, and sorry, I'm likely to bomb the server with 
questions. Please forgive me in advance
