Files
Files are often very difficult for beginners to visualise. I use a
roll of exposed film
to denote a sequential file. This has lots of little compartments the
same size one right after each other, and they are even numbered.
In order to demonstrate the difference between the name of a file
and its handle in the program, I put a
piece of paper at the top with two names
on it, one that the program sees and one for the file itself.
