probability batch programs

Hey all, I have very little computer knowledge. I'm trying to write a batch program that will pick a random number between 0 and 1. If the number is between 0 and .2, i want the batch program to run one set of commands, if not, a different set. I'm sure this can be done, it's probably QUITE simple. But i dunno how -- so can someone tell me? Pleeeeeeease? (E-mail would be the best way to answer, but I'll check here too).

Standard DOS batch does not support random number generation. In fact, it has no 'built-in' support for any type of arithmetic. You either need to either a) find a 3rd party piece of software that will generate a random number and pass the value to an environmental variable or b) write a program yourself to do it. Qbasic is probably the easiest way.

This batch will not give you technically random numbers, but random for most practical purposes.
