The appeal is from an order denying what was treated in the Superior Court as a motion for postconviction relief (Mass.R.Crim.P. 30[a], 378 Mass. 900 [1979]) with respect to the sentences which were imposed on the defendant following his testimony for the prosecution in a case of murder and armed robbery. See Commonwealth v. Gilday, 367 Mass. 474, 477, 480-482, 489-491 (1975), S.C., 382 Mass. 166, 169-170, 178 (1980).

None of the "loans" of the defendant to the Federal authorities operated as a pardon of any offence (Ladetto v. Commissioner of Correction, 373 Mass. 859, 859 [1977]), nor is there any merit to any of the other contentions raised by the defendant. See, e.g., Ponzi v. Fessenden, 258 U.S. 254, 255-256, 269-260, 265-266 (1922); United States ex rel. Demarois v. Farrell, 87 F.2d 957, 962 (8th Cir. 1937); In re Liberatore, 574 F.2d 78, 89 (2d Cir. 1978).
Order affirmed.
