PER CURIAM.
Appellants appeal a workmen's compensation order which is hereby affirmed, with the observation that the computation of social security offset is regarded as self-executing in nature and failure of the judge to adjudicate the issue does not constitute reversible error. Capital Lincoln Mercury, Inc. v. Knowles, IRC Order 2-3756 (April 6, 1979); Aero Corporation v. Raulerson, IRC Order 2-3700 (February 15, 1979).
McCORD, Acting C.J., and SHAW and WENTWORTH, JJ., concur.
