Axe really could use a command to generate an integer in a specified range. I think that's been on the to-do list for a long time, but getting it to work in an optimal fashion is a bit tricky. So it remains unimplemented...

Anyways, you can still generate a random integer in a certain range with rand. And you might kick yourself when you hear that, although the necessary information is a bit fractured, you can glean this technique from the Documentation.pdf file:

• Page 13: This code block uses rand^88 and rand^54 to generate random X and Y coordinates, respectively. The sidebar mentions that "the easiest way to get random numbers is to take the modulus with X to get a random number between 0 and X-1." So the first snippet generates a random integer between 0 and 88-1=87, and the second generates a random integer between 0 and 54-1=53.
• Page 18: The last code block uses rand^512-256 to generate a X random velocity. By following up the modulo operation with an addition/subtraction, this generates a random integer between 0-256=-256 and 512-1-256=255. In the general case: rand^A+B generates a random integer between B and A+B-1.

Yep, years of experience. Looking at my post history, I've been using Axe for just over 5 years now. And when I started, I also asked a bunch of questions. So you're on a good track.

By the way, if you want to ask somewhat simple questions like these in the future (which are totally fine; good, even), I'd recommend asking in the Axe Q&A thread instead of making a topic for each one. Having one thread concentrated with questions and answers is a lot nicer than a bunch of individual topics that die off within a few posts. You can even just browse around the thread as a kind of grab-bag Axe documentation that covers practical information and techniques that may not be documented elsewhere.
