NAME
       createablunaryexpr - creates an unary operator expression.


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

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 );
