This is an appeal from the denial of a motion filed pursuant to 28 U.S.C. § 2255, alleging that the prosecution knowingly used perjured testimony, that appellant did not have effective assistance of counsel, and that the trial judge lost jurisdiction to proceed to judgment because of erroneous rulings. The District Court held that the files and records in the case conclusively showed that the defendant was entitled to no re *227 lief, and that certain of the claimed errors could only be raised by direct appeal. *

On the materials before us, we find no error affecting substantial rights. Cf. Wilkins v. United States, 1955, 97 U.S.App.D.C. 66, 228 F.2d 37.

Affirmed.
