And the program NEVER DOES THAT WITH THE LAST
POINT BECAUSE THE PLAYER DOESN’T KNOW HOW
TO GET THE LAST POINT.

Only if the player gets the last point and by definition
when the player doesn’t know how to get the last point,
the SET BREAK on that last point never happens.

> The address break will happen and stop the program.

ONLY if the player GETS THE LAST POINT and by definition that
will never happen because the player doesn’t know how to do that.

No you can't when the player never gets the last point.

> You can also determine which room the actions need to happen.

ONLY by examining the code, NOT by using SET BREAK on the
last point data. Because by definition the player never gets the
last point because they don’t know how to do that.
