strange particle production

[Gauri199]

how can we set status for k short , lambda, Xi, and omega particle production in pythia8239?
I have tried to add a status command in mainxx.cc file- if((pythia.event[i].isFinal()) && (pythia.event[i].status()) && pythia.event[i].isCharged())
{
int stat = pythia.event[i].status();
if (stat > 0) pythia.event[i].status(-stat);
{ after in loop we calculate pT, eta, Yrap,E .
After that, we read pyroot.root file and plot for charged and final state particles (pion, kaon, and protons). we found better results for charged particles.
