I sent Rob a simple 7-character unique filename generator the other day. It was
inspired by CChris's recent "unique_filename() function".

"uniquefilename.e" is based on the Euphoria date() function -- every second a
new name is generated with no repeats -- at least for the next 25 years.

There's room for tweaking, so...

That's what I did. But instead of a "ddmm" or "mmdd" sequence, I used the day of
the year ( date[8] ) from the date() function. That's easier to code (and decode)
as well as shorter than "mmdd" or "ddmm".

The result is [year][day of year][seconds of day] translated into base 26 (A-Z),
for a total of 6 characters.

Thanks for the comments,

Doesn't seem to be working for me. It's only generating unique filenames every
5-10 seconds.
