When you pass no arguments, this won't execute as args.length
will still be 1, the only argument being the path to the
executable -- args[0], of which you are apparently already aware.
The if conditional should be this to test for no args:
if(args.length == 1)
string op = args[1];
Because the above conditional passes when you pass no args, this
causes a range violation since args[1] doesn't exist.
