SYNOPSYS

       #include "bdd101.h"
       bddindex getbddvarindex( BddSystem, Variable )
	 bddsystem *BddSystem;
	 bddvar     Variable;

PARAMETERS

       BddSystem	   The bdd system.

       Variable 	   The variable number to convert.

DESCRIPTION

       getbddvarindex converts the variable number Variable to a bdd index, in the bdd system BddSystem.  If a null pointer is given, the  default
       bdd system is used.  The function uses simply the translation table BddSystem->VAR_TO_INDEX.

RETURN VALUE

       getbddvarindex returns the bdd index of Variable.

ERRORS

       "variable xxx out of range, error !"
	      The Variable parameter must be less or equal to the BddSystem->NUMBER_VAR field.

EXAMPLE

       #include "bdd101.h"
	  bddsystem  *BddSystem;
	  bddnode    *BddNode;
	  BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
	  BddNode = addbddvar( (bddsystem *)0, 0 );
	  /* displays 2 */
	  printf( "%d", getbddvarindex( (bddsystem *)0, 0 ) );
	  destroybddsystem( (bddsystem *)0 );
