"break" in script exits all loops--ends script

ROOT
1

based on the a class generated with “MakeClass”, I modified the Loop() to print out values for a particular cut. I have a nested loop. When I include the “break” line listed below the break statement breaks out of both loops and ends the script. If I comment out the break statement it seems to work correctly, however it doesn’t fill my array correctly.

Anyone experience problems with this before?

#define getLundIds_cxx
#include "getLundIds.h"
#include <TH2.h>
#include <TStyle.h>
#include <TCanvas.h>

void getLundIds::Loop()
{
  const int ARRAYENTRIES = 50;
  Int_t lundid[ARRAYENTRIES][2] = {0};

  int j = 0;
  int test =0;

  Int_t Ks0LundId_MC;
  fChain->SetBranchStatus("*",1);
  fChain -> SetBranchAddress("Ks0LundId_MC", &Ks0LundId_MC);

  TCut cut = "d0Mass > 1.78 && d0Mass < 1.94 && pi0PCms > 0.96 && KsMass > 0.492 && KsMass < 0.502 && dStarPCms > 2.79 && kstightmassbackground == 1 && Ks1E_MC == pi01E_MC && delMass > 0.1445 && delMass < 0.1463";

  fChain -> Draw(">>inEvList", cut);
  TEventList *ev = (TEventList *)gDirectory->Get("inEvList");
  Int_t nentries = ev -> GetN();

  for (Int_t jentry=0; jentry<nentries;jentry++) {
    fChain->GetEntry(ev->GetEntry(jentry));

    for(Int_t i=0;i<ARRAYENTRIES;i++)
      {
        if(lundid[i][0] == Ks0LundId_MC)
          {
            lundid[i][1]++;
            //      break;  //<-------- This Is tHE liNE
          }
        else if(i == (ARRAYENTRIES-1))
          {
            lundid[j][0] = Ks0LundId_MC;
            j++;
          }
      }
  }

  for(int k=0;k<ARRAYENTRIES;k++)
    {
      cout << k << ": " << lundid[k][0] << ": " << lundid[k][1] << endl;
    }
}

Hi,

Which version of ROOT are you using? A priori you can work around the problem either by disable the CINT optmization (.O 0) or by compiling the script with ACLiC (.L myscript.C+).

Cheers,

I’m using 5.17, but I’ll try upgrading.
