Hmm .. Sounds great ! Is is the same spec. that may be found on Fish 247 ?
I can't get to Bix from France, but now that we have a CBM BBS for
developer support in France (also in other European countries I believe),
I think it would be a good idea that this kind of documents should be 
forwarded regularly to these sites.
I'm not sure what the exact procedure should be, but maybe we can work it 
out. 
In my opinion, the whole thing (VLT, XPRs) is really good work, and should be
advertised. I'm anxious to see if XEMs make sense in a BBS context, as sure 
as XPRs do !

Ok I buy this solution. The library solution would introduce more stubs,
and is in fact too heavy for such a light work.
There are already so many "interfaces" because all specifications are 
based on parameter passed in registers, and most of the code is written 
in C.

Thanks for these explanations. Thanks also to others who followed the
discussion.
