A few of the middle school gyms are dating back to before the 3-pt line came into existance.

Now for free throws without the three-pt line, what restrictions were there for players who were not in a marked lane space?

The same as for courts with the 3 pt line.:D

You can't call it any other way, just eyeball it and call the obvious violations.

On an illegal court without a continuous division line are you going to not call a backcourt or 10 second violation because the line is not there?

Well even if I don't call it that way, I'm still curious as to how it used to be.

You mean
 

I can only wait for Jurassic to jump in here... But as I recall in THOSE DAYS... You were actually allowed to line up 4 players on each side of the key... That allowed for 8 of the 10 players... the free-thrower was nine... And the 10th was always in the backcourt standing there looking good and I don't believe anyone ever thought he/she was in danger of breaking into the free-throw area after the release, after it struck the rim, or even after it hit the floor. :p
But I believe that in the event he/she got curious enough to move in closer, he/she was restricted by the free-throw lane arc above the free-thrower and the free-throw line extended..

ref18:

Since there are no three-point lines on the court I am going to make the educated assumption that the league in which the school competes does not use the three-point field goal. There is one league in SE Michigan that does not use the three-point field goal at the jr. H.S. level and the courts do not have the three-point lines on the court.

Jr. H.S. games in this league revert back to the pre-three-point field goal rules for free throws with regard to players on in marked lane spaces. Those rules state that players not in marked lane spaces must be behind the free throw-line extended and the free throw circle.
