TI-83/84 Plus series - Amount of free RAM?
« on: October 23, 2010, 10:49:33 pm »
I may be mistaken, but is there not a byte pair in RAM in which the OS keeps the amount of free RAM? If there is, where in RAM is this located, and how often is this value updated? If not, I'll just use MemChk, but this seems easier.

I knew there was a way of finding it, and looking at that post I actually remember seeing it before. Thanks for finding it for me.

Oh, didn't see that. Thanks!

What do the byte pairs hold, anyway?

No, they are the pointers to the operating stack and the floating point stack. All free RAM is located between these two structures, so subtracting the pointers to them makes sense that it would give you the amount of free RAM.

I didn't knew about that part, lol. I never tried that stuff so I always thought both addresses contained the total user RAM in 2 byte format.
