Title: TI-83/84 Plus series - Amount of free RAM?
Post by: Runer112 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.

What do the byte pairs hold, anyway?

Total RAM and used RAM, maybe? s:
