Hello Rooters, I have a minor suggestion which results from numerous pilot errors of mine which I'm making regularly when using the code generated with TTree::MakeClass. Here is the deal. The autogenerated code uses `i' as an index to loop over the tree entries: for (Int_t i=0; i<nentries;i++) { if (LoadTree(i) < 0) break; nb = fTree->GetEntry(i); nbytes += nb; ....... place for the user code .......... } One of the first things I'm normally doing within this loop is creation of a (nested) loop over the objects stored in the event (i.e. tracks). And a preferred choice for the index of the inner loop for me is also `i' with all the easily predictable consequences... In case I'm not alone - wouldn't it make sense to name the index variable of the autogenerated loop something like `ientry' rather than `i' ? thanks, pasha
