2017-18 Basketball Comments on the Rules
New rule for officials to issue a warning (4-48-1 and 2): Officials may now issue a warning to the coach or the team bench. These warnings can be for conduct that is described in 10-5 or 10-6. If the offense is deemed to be major, the official may assess a technical foul in either situation. A warning is not required prior to assessing a technical foul. These warnings will be recorded in the scorebook by the scorer and reported to the head coach.

2017-18 Basketball Rules Interpretations
Situation 13: The head coach of Team A is upset that the foul count against his team is 7 to 2. He voices his opinion in an unsporting manner to the contest official. Ruling: The official should stop play if it is not a break situation with a potential scoring opportunity and give the coach an official warning by notifying the scorekeeper and then letting the coach know that he has been warned. The scorekeeper should make note of the warning in the scorebook. This situation does not have to be given a warning; the coach could be issued a technical immediately. (4-48)

Situation 14: During a live ball, the assistant coach is off the bench and out of the coaching box giving instructions to a player on the court. Ruling: The official should rule a technical on the assistant coach for being off the bench and out of the coaching box. (4-48)

Situation 15: During the second quarter, the head coach is off the bench expressing his disapproval of several calls made. As the team brings the ball down the floor into the frontcourt, the trail official stops play to issue a warning. Ruling: The official is correct in issuing a warning to the coach for the complaints. The scorekeeper is notified, as well as the coach, of the warning. Another warning cannot be given. (4-48)

Unless I'm missing something, no where does the NFHS state that a bench technical foul without a previous warning means that the bench has lost the privilege of getting a warning later in that game.

Is it because of this: For the first violation of Rule 10-6-1, the official must warn the head coach unless the offense is judged to be major, in which case a technical foul must be assessed, and in my situation it would be a second violation?

But again, is there a need for the official to instruct the scorekeeper write a behavior warning, a warning that really wasn't given, down in the book, as stated on the IAABO quiz (to charge both a technical foul and to issue a behavior warning)?
