My first program created a sequential text file.  My next program
will read the sequential text file that was created, record by
record, formatting the output of each field, and sending that to stdout.

This may not have ANY use in the real world!  I certainly haven't been
able to find ANY examples in either my C textbooks (I have several on
my reference shelf), my C reference books (I have several on my shelf --
I did find the strtok() example in a reference book), or online.  Maybe
this is just an exercise that I want to do in order to learn about text 
files, arrays, strings, and/or pointers? I do think it is related to the
last few Beginner's Lessons, but _PCP_ is woefully lacking in examples
for doing this sort of thing. *I* seem to do much better with an example
to modify and play with, especially at this point in my C education.
