However, it's performance leads me to believe it isn't as random as I thought at first, there definately appears to be some form of pattern in the output. That reminds me of back when I played with C++, I once read that the randomize function in C/C++ actually uses the computer's clock in some way ti seed the function. I also remember there was a way to go around it so you get a real random number. Anyone have any hints on how to make $rand pick a real random number? DALnet #Helpdesk I hear and I forget.

But I'm not sure. Ironically, I don't know how to do what you're wanting, I just thought I'd throw in my 2 cents. Experience The Void.. Are You Ready?

So then we return to the original question: How do I get a truly random number. DALnet #Helpdesk I hear and I forget. I see and I remember. I do and I understand. -Confucius

I know that you can't self seed in mIRC - but maybe a random loop ( e.g. loop for $rand(1, 100) times) would stop on a random 'tick' which makes it less predictable.
