CREATEABLBINEXPR(3)              ABL FUNCTIONS             CREATEABLBINEXPR(3)



NAME
       createablbinexpr - creates a binary operator expression.


ORIGIN
       This software belongs to the  ALLIANCE CAD SYSTEM developed by the ASIM
       team at LIP6 laboratory of UniversitÃ© Pierre et Marie CURIE, in Paris,
       France.

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 );
