will print out all the settings stored in the db, including the one you are interested in.

Thanks voor the pointer. I have made the following change, line is broken into multiples for readability:

start /wait calibre-debug -c "
from calibre.library import db; 
db=db(); 
from calibre.utils.config import prefs; 
ids = db.prefs.get('news_to_be_synced', set([])); 
ids.append(%id%); 
db.prefs.set('news_to_be_synced', ids);
"

How does that look to you?
Any room for improvement?

Thanks,
