Sean,
>My question is regarding how does CINT deals with command line arguments ?
Yes, it does. Just the same way as the compiled C/C++ program hadles the
arguments.

This is a very interesting notation. It is not supported by cint and neither
by other C/C++ processing systems, this inspires me.
I guess your expectation is that , like perl or shell script, a script
interpreter should execute commands out side of function scope. This mechanism
is used by other script interpreters and it plays a role of main function.
Cint handles C/C++ code, so the entry point is main() function rather than
statements appears in global scope.
In this case, to do what you want, suppose you have cmd.C as follows
// cmd.C /////////////////////////
#include <iostream.h>
main(int argc, char* argv[]) {
for(int i=0; i<argc;i++){
cout << argv[i] << endl;
}
}
// end of cmd.C //////////////////
Start cint or ROOT and use the command as follows.
root[0] .L cmd.C
root[1] char *argv[]={"main","abc","def"};
root[2] main(3,argv);
Or use raw cint interpreter from UNIX or DOS command line,
$ cint cmd.C abc def
This will do.
