> I have a stopwatch function in my HP48 that I don't want using a local variable (avoid polluting my precious menu), or having to keep it in a stack.
The first thing that comes to mind is that there's a hidden directory at the root that the ROM itself uses to store stuff like this. This link talks a bit about how to get there:
This uses SYSEVAL to call into a normally-not-visible object that puts the name of the directory on the stack. From there, you should be able to read/write the variable.
You may also be able to do some hacky stuff with self-modifying code, but that's honestly something I'd avoid unless you want to try it for fun.
Not at all.
