I thought that some Axe programmers would find it useful to be able to run archived programs. Also, the Asm( sequence I posted to run programs in RAM will leak memory if the program you call throws an error. So I wrote an Axiom that lets you run other assembly/Axe programs and fixes memory leak issues. If you want, there's even a provision in there that lets you prevent your subprograms from being run from anything other than this Axiom, in case they do nothing useful on their own. Additionally, it also lets you catch errors that the OS may throw; that is, it lets you prevent that ERR: screen from showing up. The attached ZIP file contains the Axiom, its source code, and all the documentation. I'm a little afraid that the part of the documentation about error handlers is a little unclear, so if you're confused, feel free to ask questions.
Quigibo and Runer112: Feel free to optimize this---I'm sure it can be---and put it in Axe.
Here's an example. Let's say you have a fancy intro screen that's very large. You want it to run if the user has it---regardless of whether it's archived or in RAM---, but you want your program silently to skip running the intro screen if it doesn't exist. Just put this code in the main program:
