         bddsystem ∗BddSystem;

PARAMETERS
       BddSystem           The bdd system.

DESCRIPTION
       addbddvarfirst creates a new variable, with the number 0, in the bdd
       system BddSystem.  If a null pointer is given, the default bdd system
       is used.

RETURN VALUE
       addbddvarfirst returns a pointer to the bdd node of the new variable.

ERRORS
       "no more variables, error !"
              There is no variable number left.

EXAMPLE
       #include "bdd101.h"
          bddsystem  ∗BddSystem;
          bddnode    ∗BddNode;
          BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
          BddNode = addbddvarfirst( (bddsystem ∗)0 );
          destroybddsystem( (bddsystem ∗)0 );
