My understanding has been that handles became necessary when OS systems began
to do memory housekeeping. A pointer might be viable before the housekeeping,
and afterwards not. Handles allowed the system to re-reference the new location
of the data in memory.

I was kidding. I gave up on Pascal when I got to building GUI's and using the
system API's. I saw immediately that unless I was going to program for a
living, it was all just too much to assimilate along with everything else
pertaining to IT that I had to know day to day.

The difficulty with point
The difficulty with pointers and handles was that with one you could get
straight at the value you wanted, and the other you had to dereference it
first. Meaning, that you were the one who had to understand whether you were
dealing with a pointer or a handle. Computers ought to take care of thos
I don't know why you would have a problem with that;
Once you understand how to use pointers, you should have no problems with
handles;

When I was learning Pascal, I discovered that a handle was a pointer to a
pointer. When I learned why that had to be, I decided to stick with Hypercard.

You can use something similar to pointers going one direction by using
"value", and the other way by using "do". Those are not full-on pointers,
but it does give you some indirection. While sometimes it would be nice to
have regular pointer syntax (but in a LC syntax way), at least you can get
