NAME

       createablbinexpr - creates a binary operator expression.

SYNOPSYS

       #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 !",
              Operator must be defined and must be a binary operator.

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 );
