   Here's a shocker, IBM supports it because it is part of AT LEAST the XPG4
   standard. :)

here's a shoker: it's actually a good idea. :-)  ASCII and EBCDIC are, after all, not
everything.

question: tr was often used to implement the usenet rot13:
    tr [A-Za-z] [N-ZA-Mn-za-m]
is there a way of doing that with this portable notation?  there's some way
of specifying a subrange, surely.

do we need an alt.lang.tr group?  :-)
