The only error presented in this appeal is whether the trial court erred in failing to charge without request on the impeachment of the appellant as a witness. We find no error. Harvey v. State, 233 Ga. 41 (4) (209 SE2d 587) (1974); Williams v. State, 222 Ga. 208 (149 SE2d 449) (1966).
Judgment affirmed.
All the Justices concur.
