Of course, I could just test the length and then use substr it all out, or even
sprintf it into a new variable with a pad at the first character.
But this is perl, and I reckon there are much cooler ways to do it.
Any takers?

My hash has keys that are dates in "ddmmm" format (21Jul2001).
I would like to sort the hash by date.
So as I understand it:
keys %dates
should return an array with the dates in. I can't sort that directly as it is a date,
so I was thinking that I could split the date out and timel
nth, and four for the
>year.

Hmm... this used to work in old dos:
cls > clear.txt
type clear.txt
This would clear the screen. Now you just get an ascii representation of the clear
code.
Does this mean than that you cannot clear the screen in Win32 just by printing an
ascii sequence?
Or perhaps we need
device=c:
t it
into the loop. Or perhaps I shouldn't.
Can you help further?
Thanks,
Paul.

This returns the headers of each message. From those you could analyse and count the

Okay, this is a seriously wierd constructm lol... =o)
First of all "last until" is a logical oxymoron. "last" breaks out of a
