Don't know about useful, but interesting... Well, how about the self
printing batch program that I posted to alt.hackers some time ago:

SELFPRNT.BAT:
	Bad command or file name

It is particularly nice since:

	a. It can be made arbitrarily long
	b. Its existence doesn't follow from the recursion theorem.  

The recursion theorem states that any programming language with
very minimal features: increment, pairing, if, goto's, etc. has a
self-printing program. DOS batch programming is not a language in
this respect.  Is it a programming language at all?.

And yet another teaser: The above batch file doesn't self print
on 4DOS!
