I know how to do this in PL/I, but despite having spent the last two hours
paging through a C language reference manual, I couldn't find any examples
of overlaying two structures. I did find reference to something called

Yes thats absolutely right. Remember since C is a powerful, low level, and untyped programming language untagged unions are consider unsafe.

Good luck though!
