Ask: how to transfer the parameter for the root scritpt

Hello rooters, I will use an example to show my question: my root script (DrawDiLepPlots.C) is like following: void DrawDiLepPlots(int period=-1 ) { cout<<" period: "<<period<<endl; } If you run command-“root DrawDiLepPlots.C”, the output is: period: -1 May I ask how could I change the period by this command line mode?
