23−As we mentioned in the previous lesson, the easiest way to use such a program is to run it as a _generator_. Mount your desk `|mount %` (if you didn't do it before), saving a file in the `/home/gen` directory of your ship and commiting these changes `|commit %home` allows you to run it from your ship's Dojo (command line) as a generator. Save the above code there as `list.hoon`. Now you can run it in the Dojo with the command below (remember, without the `>`):

If these values are equal, we want to end the program, because our list has been built out to where it needs to be. Note that this expression is, in fact, a rune expression, just written a different way than you've seen so far. `=(end count)` is an _irregular form_ of `.= end count`, different in looks but identical in operation. `.=` is a rune that checks for the equality of its two children, and produces a `true` or `false` based on what it finds.
