Violations.....or not?

[Illini_Ref]

NFHS rules. Can someone give answers and references please?

1. A1 saves a loose ball near the sideline. He saves it inbounds. The ball touches the court. A1 runs back inbounds and continues the dribble. A1 had not dribbled the ball prior to this play, he just saved a loose ball.

2. A1 saves the same loose ball. He gets back inbounds and catches the ball before it hits the floor.

3. A1 is dribbling down the sideline. He is loosing his balance OOB so he steps out of bounds and back in and continues dribbling.

4. A1 is dribbling. B1 slaps the ball away and A1 saves it as in sitch 1.


I know for instance that 3 is illegal. However, is it called whent eh dribbler goes OOB, or when he returns and touches?
