The appellant was tried before the court without a jury and found guilty of the sale of heroin. The proof of appellant’s guilt was overwhelming. On this appeal he claims two procedural errors. Each ruling urged as error was within the sound judicial discretion of the trial judge and error has not been demonstrated. See Floyd v. State, Fla.1956, 90 So.2d 105; Matera v. State, Fla.App.1969, 218 So.2d 180.

Affirmed.
