App. 390, 393-94, 308 S.E.2d 910, 912-13 (1983), the Court concluded the trial court did not prejudice defendant by summarily denying defendant's motion to dismiss in the presence of the jury. "Generally, ordinary rulings by the court in the course of trial do not amount to an impermissible expression of opinion." Id. at 393-94, 308 S.E.2d at 913.
