I got it and installed it.  Thank you for advise it looks a lot more
sophisticated than mine is. The Object awareness that I needed was for
a game.  My turtle is in the maze and is trying to get out through
openings in the maze.  If it hits the wall, I wanted it to turn around
and walk in a different direction.  I need to know when turtle will
hit the wall, and where it has happened.

If two shapes colide on the screen, are they aware of each other.
How
can
I know  that one shape collided with another and at what point.
For example, if the turtle hits square, how can I know the exact
position of
the
collision on the outside perimeter of the square?

If by "shapes" you mean: pictures with which you dress the turtle
using
the

setsh

command. Then yes.

You can detect collisions with:

if touching "t1 "t2 [...]

for example:

if touching "t1 "t2 [show ask "t1 [pos]]

which shows the position of t1 at the time of collision with t2.
