const Vector<String>& cl = CommandLine();

and before you ask

SetExitCode(...);

(if you do not set exit code, it is 0).

Thanks,

this works:

int argc = CommandLine().GetCount();

const Vector<String>& argv = CommandLine();
		
var1 = argv[0];
var2 = argv[1];

By the way... is there any documenation about these packages?

Another problem:

when i try to get the first agrument like this:

int argc = CommandLine().GetCount();
const Vector<String>& argv = CommandLine();

if(argv[0]=="/?")
  {
    std::cout << "Syntax: blah blah blah" << "\n";
  }

i got an EXEPTION_ACCESS_VIOLATION reading at 0000000E.

What's wrong?

if((argc >= 1) && (argv[0]=="/?"))

BTW, try DEBUG mode sometimes, there's an ASSERT macro in Vector code, which will tell you you are trying to access member outside of current vector size.
