NAME

createablbinexpr - creates a binary operator expression.

See the file man1/alc_origin.1.

SYNOPSIS

#include "abl101.h"
chain_list ∗createablbinexpr( Oper, Expr1, Expr2 )


  long        Oper;


  chain_list ∗Expr1;


  chain_list ∗Expr2;

PARAMETERS

Oper

The operator number.

Expr1

The first expression.

Expr2

The second expression.

DESCRIPTION

createablbinexpr creates the binary operator expression Expr1 Operator Expr2. If the operator of Expr1 and/or Expr2, and Operator are identicals createablbinexpr merges eventually the sub-expressions. The expression pointers Expr1 and Expr2 MUSTN'T be used after the call to this function.

RETURN VALUE

createablbinexpr returns a pointer to the new operator expression.

ERRORS

"ablcreate: bad operator xx !",

EXAMPLE

#include "abl101.h"


   chain_list ∗ExprA;


   chain_list ∗ExprB;


   chain_list ∗ExprAorB;


   ExprA = createablatom( "a" );


   ExprB = createablatom( "b" );


   ExprAorB  = createablbinexpr( ABL_OR, ExprA, ExprB );
