I've been looking through the TI-83+ documented rom calls, and found a bunch of calls that closed/destroyed the edit buffer. However, I found none that opened it.
How do you open the edit buffer?
Also, how do you access it (where is it located), and exactly how big is it? |

I believe the edit buffer is used for getting input of (ideally) any size from the user. Once you figure out how to open it, it shifts programs around so that all free RAM (not counting safe RAM areas) is in one block, and some system variable holds a pointer to the start of that block. Then you read stuff in, or I guess you could really do anything else you want with it, then close it when you're done.
I don't really know the details. But I believe _EditProg and _CloseProg are used in a similar process, and the rom call documentation does a much more thorough job of explaining these.
If you had the TI developer guide on hand (which I don't), Chapter 2 seems to be the one to read.

Hm, after looking on Google (it helps, really), I have the gnawing suspicion you only use it for hooks. That is, the 'edit buffer' is the home screen.
But that's just a suspicion.
You should also look here: http://wikiti.denglend.net/index.php?title...ame:Edit_Buffer

| I found a flag called [font="courier new;font-size:9pt;line-height:100%;color:darkblue"]EditOpen,(IY+EditFlags). Can I just set this, and turn on the edit buffer that way? |

I strongly doubt it, since we don't know where it is.
Besides, when the edit buffer is open, the TIOS shifts all the memory available around, and it's certainly not going to do it just because you set a flag.

Sorry for the necropost (wow, 4 years, seriously?), but basically, [bump]. I can't find any info on it either  |
