SYNOPSIS
       #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 );
