Module inquiry: random id / variable

[icqheretic]

Hi all. Just fielding a question. Anyone know of a module that will set a random number?

For example:
seedrandom on;

The goal is to have the value stored / accessible throug a variable:

$randomid

Just wondering if such a module exists and if not, suggestions on a starting point -- perphaps a module that does something similar?  Time is pressing here, so I'd rather modify as little as possible.

Thanks for reading!
