Interestingly enough, it may be useful to know - for those who don't know - that setting alarms 0 thru 11 without actually having an alarm execution event will not cause that alarm to count down, so if you don't have any really specific variables you need, you can just use alarm[0] thru alarm[11] without their execution events to save some memory (because the memory for alarms is already allocated into the RAM when the room starts). On a related note, setting alarms 12 or higher, which have no alarm execution events at all, will cause them to count down each step. I don't think you can make them count up, but if you run out of alarms to use or just need something to perform a countdown, you can use alarm[12] or higher indices. These will stop at -1
