HI ,
how can I get access from within a macro function to a TTree which was
loaded interactively from an hbook converted file?

root[21] Int_t BGOList[3] = {1,2,3};
root[22]  f1 = new TFile("MyFile.root");
root[23] .L GainHV.C;

root [24] f1.ls();
TFile**         bt416_05_eve.root
 TFile*         bt416_05_eve.root
  KEY: TTree    h10;1   event
root [25] GainHV(&BGOList, 3)

Error: No symbol h10.Print() in current scope
FILE:/data/norbert/proc/root/macros/
GainHV.C LINE:62
*** Interpreter error recovered ***

Thanks,

Norbert
