dissenting.
The conviction should not be reversed on the ground set forth in the majority opinion. No harm has been shown or that appellant has not obtained a fair trial. Error in a charge should not cause a reversal unless it is calculated to injure the rights of a defendant as provided in Article 36.19, U.A.C.C.P. See the dissenting opinion in Cleland v. State, 575 S.W.2d 296 (Tex.Cr.App.1979).
