RAM used by OS on 84+ 2.53
« on: October 01, 2011, 01:18:41 pm »
I found a page on WikiTI that described what areas of RAM (on RAM page $83) were used for MathPrint and other stuff.  I don't remember where that wikiti article is now, can someone post a link?

It's a bit out of the way, but that's where it's at. If you search 2.53, you might have a 1 in 10 chance of finding it ;D (Sadly, that's not even sarcasm)

You can build a statue out of either 1'x1' blocks or 12'x12' blocks. The 1'x1' blocks will take a lot longer, but the final product is worth it.

If a user is in classic mode rather than MathPrint mode, is the RAM from 977Eh–9D7Dh free to corrupt?

No, only 9A7Eh–9D7Dh is safe. The OS still stores the entries there.

On another note, the entries menu is small enough that you can just throw it in saveSScreen, and replace it when you are done. (That's what I do.)

I don't think so, since even in Classic mode it stores the last entries there (somebody feel free to correct me if I'm wrong). Well, at any rate you can trash the last 768 bytes in either mode, as long as you zero that buffer before exit.
