Defendant was convicted of breaking and entering an occupied dwelling with intent to commit the felony of rape, contrary to MCLA § 750.110 (Stat Ann 1971 Cum Supp § 28.305), and assault with intent to do great bodily harm less than the crime of murder, contrary to MCLA § 750.84 (Stat Ann 1962 Rev § 28.279). He was given concurrent sentences on the two convictions. The people move to affirm defendant’s convictions. GrCR 1963, 817.5(3).

It is manifest that the questions presented, upon which decision of the cause depends, are so unsubstantial as to need no argument or formal submission. Our examination of the trial transcript satisfies us that the trial court’s interruptions of defense counsel’s examination of witness was within the statutory prerogative of the trial court “to control all proceedings during the trial, and to limit the introduction of evidence and the argument of counsel to relevant and material matters, with a view to the expeditious and effective ascertainment of the truth regarding the matters involved.” MCLA § 768.29 (Stat Ann 1954 Rev § 28. 1052).

Motion to affirm is granted.
