SYNOPSYS

#include "abl101.h"
chain_list ∗createablunaryexpr( Oper, Expr )
  long        Oper;
  chain_list ∗Expr;

PARAMETERS

Oper
The unary operator number.
Expr
Expression.

DESCRIPTION

createablunaryexpr creates the unary operator expression Operator Expr. createablbinexpr combines eventualy the operator of Expr with Operator. The expression pointer Expr MUSTN'T be used after the call to this function.

RETURN VALUE

createablunaryexpr returns a pointer to the new operator expression.

ERRORS

"ablcreate: bad operator xx !",
Operator must be defined and must be a unary operator.

EXAMPLE

#include "abl101.h"
   chain_list ∗ExprA;
   chain_list ∗ExprB;
   chain_list ∗ExprAorB;
   chain_list ∗ExprAnorB;
   ExprA = createablatom( "a" );
   ExprB = createablatom( "b" );
   ExprAorB  = createablbinexpr( ABL_OR, ExprA, ExprB );
   ExprAnorB = createablunaryexpr( ABL_NOT, ExprAorB );
