Kinda hard to sort on a numeric field that way tho, which I think he
wanted...

: Just in case you dont have reverse... It is easy to write!

It's even easier than a 97 line C program:

    perl -ne 'chop; print reverse "\n", split(//);'

But probably not as efficient.  Especially if you include the time to
install perl.   :-)
