SYNOPSYS¶

#include "abl101.h"
chain_list ∗substablexpr( Expr1, Name, Expr2 )


  chain_list ∗Expr1;


  char       ∗Name;


  chain_list ∗Expr2;

PARAMETERS¶

Expr1

First expression.

Name

Atom name.

Expr

Second expression.

DESCRIPTION¶

substablexpr substitutes Atom in Expr1 by Expr2. The expression pointer Expr1 MUSTN'T be used after the call to this function.

RETURN VALUE¶

substablexpr returns the modified expression.

EXAMPLE¶

#include "abl101.h"


  chain_list ∗Expr1;


  chain_list ∗Expr2;


  Expr1 = createablbinexpr( ABL_OR,


                            createablatom( "a" ),


                            createablatom( "b" ) );


  Expr2 = createablbinexpr( ABL_AND,


                            createablatom( "c" ),


                            createablatom( "d" ) );


  Expr1 = substablexpr( Expr1, "a", Expr2 );


  /* displays ((c and d) or b) */


  viewablexpr( Expr1, ABL_VIEW_VHDL );
