I probably shouldn't do this but by posting this amateurish
code some of the beginners some of my fellow hobbyists who are also
trying to learn something might be encouraged or see something to
criticize or make the basis for discussion.  There are possibly
bugs in it of which I'm still unaware as it's an ongoing sort of
first real project for me.
        Kurt Kuzba was gracious enough to let me know about cprint
and get me out of a bog so I could continue and I thank him
enormously for that.  
        This is compiled with a Borland, version 3 compiler.  Look
at it carefully because I have no idea about such things as
portability yet.  I wrote it to interest the kids next door in
elementary math and in the computer which they generously take over
when they're here!!
