#include "bdd101.h"
   bddsystem  ∗BddSystem;
   bddnode    ∗BddNode1;
   bddnode    ∗BddNode2;
   BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
   BddNode1 = addbddvarfirst( (bddsystem ∗)0 );
   BddNode2 = addbddvarafter( (bddsystem ∗)0, BddNode1->INDEX );
   destroybddsystem( (bddsystem ∗)0 );
