Dear rooters
     I need to get the value of parameter Run_Number and have written a small test program as following:

{
gROOT->Reset();
  char *RUNNR = new char[100];

  sprintf(RUNNR, "export Run_Number=`getvalue runctl@krunc runnr | grep value | awk '{print $3}'`");

  gSystem->Exec(RUNNR);

  cout << "Run_Number = " << gSystem->Getenv("Run_Number") << endl;


}

The problem is the result of Run_Number is empty. But when I executed the command  

export Run_Number=`getvalue runctl@krunc runnr | grep value | awk '{print $3}'`
echo $Run_Number

I got the real value Run_Number. Could you help me?

thanks a lot                                                    Wen Mei
