No. :-)

I think you are going to have to use FindFile to
get your list of files. Then you are going to have
to sort the list. You DON'T want to use the IDL
SORT command to do that, since a unique sort order
is not guaranteed. Have a look at the BSORT
command from the NASA astronomy library. (Perhaps
someone could provide a link, I don't have it at
the moment.) With luck, that will be enough and you
won't have to resort to more aggressive string processing
techniques.

Cheers,

David
