The sole issue presented in this case is whether the trial court can alter a judgment awarding custody of a minor child during the same term without holding an additional evidentiary hearing. "[A] court has plenary control over its judgments, orders and decrees during the term at which they were made, and, in the exercise of a sound discretion, may revise, revoke, or modify them." Dover v. Dover, 205 Ga. 241 (1) (53 SE2d 492)
; Barrett v. Manus, 219 Ga. 693 (135 SE2d 430)
It follows that there is no merit in this contention of the appellant.
