[ROOT] Passing argument in ROOT

Hi rooters,

I would like to compile and execute a macro which has one parameter set by the user. How 
can I do that?

Example:
--------

Below is a very simple macro test.cc I can run in ROOT with the command:

.x test.cc++

How do I change the syntax of the ROOT instruction and of the macro to allow the user to 
set the value of the variable toto interactively ?

Thanks in advance,

Nicolas

-----------------------------------
Macro test.cc
-----------------------------------

#ifndef __CINT__

#include <stdlib.h>
#include <stdio.h>


int test();

int main()
{
  return test();
}

#endif

int test()
{
  double toto = 2.;
  printf( "toto = %g\n", toto );

  return( 0 );
}
