OVER9000! I leave no possibility uncodedfor in my nonmath programs. The unlikeliest bugs are the ones found the first, and generally are the worst *start programming rap here*

The problem is that the list can easily run thousands of bytes, and a compromise, while a great idea, would be a nightmare to implement. Add to that I'm already using Pic1....

Read is a Basic program. Macro drawings run hundreds of commands long (not helped by the fact that three of the commands use up two list elements). It takes about half a minute (I've never timed it) to Fully draw a list, and 30 seconds per undo is unacceptable.

the ability to undo ad infinitum.
Even photoshop doesn't have this 
And this should stop me...why? DJ, yeah. The only program I've ever seen advertise "unlimited undos" was HxD, which has a much easier task of it than most programs because of how densely you can store hex.
What does this program do and how does it undo? And, technically, I only need 999 undoes. If the list has any more elements than that, something's seriously wrong with the calculator. Currently, I have a save and load feature that takes a pic and notes how many list elements there are when it saves, and then truncates the list and puts the pic back on the screen when it loads.

I think you could use the algorithm of a snake.
And what algorithm would that be?

Then it'd requite saving infinite Pic Variables, but they are finite.
Hence the necessity of another method.

Before every action, you could store the screen to an OS Pic variable, and then using Undo would recall the pic var onto the screen, effectively "undoing" the last action 
But that would only allow one undo. That's not enough. I want the ability to undo ad infinitum.

My BASIC program Macro is a drawing tool. There are 8 drawing commands available, and the coordinates for each are recorded and stored, along with the command number, in a single element of LM. It's almost done, but it's missing a desperately needed feature: An undo button. I can't just do the opposite of the command that was just performed, because that could change pixels that weren't changed by the instruction being undone. The only way I can see to circumvent this situation would be to remove the last element of the list and call Read to redraw the whole thing, which would be an absolute pain. Can anyone think up a more efficient way to implement an undo feature?

[015D]"M"→Str1
GetCalc(Str1)→P
It works for me, too! Thank-you muchly! Edit: Now if only I could figure out what, exactly, P is pointing to....

Nope. Didn't work.

My brain's a little scrambled from all the documentation non-following, so what would that look like in code, exactly?

So where can I get this magical hatchet that hacks my tokens for me?

So what do I do?
Edit:
The Documentation.pdf I have explicitly states that "LABC" is the Name String for the List ABC.

If it's a problem with the first token, it's not that one. I looked at the the TI 83+ Developer's Guide and according to it, there is no difference between the way Named lists and L1-6 are stored. In the calc's eyes, L1-6 are user lists with the name of 1-6.
Edit in response to edit:
That's exactly what I'm doing now.
