EXAMPLE

#include "abl101.h"
  chain_list ∗Expr1;
  chain_list ∗Expr2;
  chain_list ∗Expr3;
  Expr1 = createablbinexpr( ABL_OR,
                            createablatom( "a" ),
                            createablatom( "b" ) );
  Expr2 = createablbinexpr( ABL_AND,
                            createablatom( "c" ),
                            createablatom( "d" ) );
  Expr3 = substdupablexpr( Expr1, "a", Expr2 );
