Hi, Dear Rooters:

I use MakeSelector to analyze some data, since these
files are very big, I want to specify total number of
events I want to process. I first did:
Global->NakeSelector("anal") then I wrote a main file
that will chain files and process all files. The main
file looks like this:

#include "anal.h"

anal *sel;
TChain ch("Global");

int main(int argc, char** argv) {
//code to chain files
ch.Process(sel);
}

Then I compile my code and run it, now I want to know
where can I specify number of events I want to
process. I know how to do it interactively
ch.Process("**.root", "", "", 10000), but I do not
know how can I do it in my way. Thanks for any help!

Best,
Tao
