EXAMPLE

#include "abl101.h"
  chain_list ∗Expr1;
  chain_list ∗Expr2;
  Expr1 = createbinexpr( ABL_OR, 
                         createablatom( "a" ),
                         createablatom( "b" ) );
  addablqexpr( Expr1, createablatom( "c" ) );
  Expr2 = unflatablexpr( dupablexpr( Expr1 ) );
  /* displays ((a or b) or c) (a or b or c) */
  viewablexpr( Expr2, ABL_VIEW_VHDL );
  viewablexpr( Expr1, ABL_VIEW_VHDL );
