NAME
       delbddnodeassoc - deletes a bdd node in a variable association.

ORIGIN
       This  software  belongs	to  the  ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
       Paris, France.

SYNOPSYS
       #include "bdd101.h"
       int delbddnodeassoc( BddSystem, BddAssoc, Variable )
	 bddsystem  *BddSystem;
	 bddassoc   *BddAssoc;
	 bddvar      Variable;

PARAMETERS
       BddSystem	   The bdd system.

       BddAssoc 	   The variable association.

       Variable 	   The variable number.

DESCRIPTION
       delbddnodeassoc deletes the bdd node associated to the variable number Variable, in the variable association BddAssoc, in  the  bdd  system
       BddSystem.   If	a  null  pointer is given, the default bdd system is used.  The number of external reference of the associated bdd node is
       incremented.

RETURN VALUE
       delbddnodeassoc returns 1 if the variable is found, 0 otherwise.

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;
	  bddcircuit *BddCircuit;
	  bddnode    *BddNode;
	  bddnode    *BddSubst;
	  bddnode    *BddVariable;
	  bddassoc   *Assoc;
	  chain_list *Expr;
	  bddvar	 Variable;
	  BddSystem  = createbddsystem( 100, 1000, 100, 50000 );
	  BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
	  Expr = createablbinexpr( ABL_AND,
				   createablatom( "i0" ),
				   createablatom( "i1" ) );
	  BddNode = addbddcircuitabl( BddCircuit, Expr );
	  freeablexpr( Expr );
	  Expr = createablbinexpr( ABL_OR,
				   createablatom( "i2" ),
				   createablatom( "i3" ) );
	  BddSubst = addbddcircuitabl( BddCircuit, Expr );
	  freeablexpr( Expr );
	  BddVariable = searchbddcircuitin( (bddcircuit *)0, "i0" );
	  Variable = getbddvarbyindex( (bddsystem *)0, BddVariable->INDEX );
	  Assoc = addbddassoc( (bddsystem *)0 );
	  addbddnodeassoc( (bddsystem *)0, Assoc, Variable, BddSubst );
	  BddNode = substbddnodeassoc( (bddsystem *)0, BddSubst, Assoc );
	  delbddnodeassoc( (bddsystem *)0, Assoc, Variable );
	  Expr = convertbddcircuitabl( BddCircuit, BddNode );
	  /* displays ((i3 or i2) and i1) */
	  viewablexpr( Expr, ABL_VIEW_VHDL );
	  freeablexpr( Expr );
	  destroybddassoc( (bddsystem *)0 );
	  destroybddsystem( (bddsystem *)0 );
	  destroybddcircuit( (bddcircuit *)0 );
