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 Oper-
       ator.  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 );
