Essentially you have it covered, except: I'd recommend first a program that
opened the file, WROTE some data and then closed it. You decide what goes
into the file, what the format is, etc, etc, and you should have a pretty good
idea what to expect in that file when the program has executed.
THEN your SECOND program essentially does the opposite. Open the same file,
read back the data and display it to confirm that you i) wrote it correctly;
ii) read it back as expected.
Do you understand the arguments to the commands listed above? ("handle",
"access", etc) Or do you need someone to run through them with you first?
