I use TTreeFormula to select interested events in a TTree. And to speed
up, I activates only those variables used in the TTreeFormula. I do it via
invoking "TTree::SetBranchStatus" one by one. It would be nice and more
convenient to have a function in TTreeFormula to activate all the variables
used inside. Thanks in advance.
BTW, Rene, what is the email address of CERNLIB team ? I want to send
suggestion on creating CERNLIB with PIC option at HP-UX. Thanks.
