thanks Seb and Benjamin

a remaining question if you would have time :

root [3] std::map<std::string,TH1*>::const_iterator hiter=hmap.begin()
root [4] std::map<std::string,TH1*>::const_iterator theend=hmap.end()
root [5] if (hiter!=theend) cout << "not the end yet" << endl;

Error: operator!= not defined for
map<string,TH1*,less<string>,allocator<pair<const string,TH1*> > >::iterator (tmpfile):1: *** Interpreter error recovered ***

i thought that this third instruction was perfectly legal

how to circumvent this ?
