The easiest way *not available until the next version* is to absorb them directly into the program.

Recall that when you have a title screen that takes up the whole screen, you don't want to have to type out the entire 1536 hex characters:
[123ABC...]

Instead, you can absorb an OS picture into the program simply by doing this:
[Pic1]

The same thing applies for tokens.  If you want a string of tokens, then instead of doing:
Data(t1,t2,t3,tA,tB,tC,...)

You can do any of these:
[Ans]
[Str1]
[prgmABC]
[appvABC]


And the data will be directly absorbed into the program, depending on where you have your tokens stored (The one with Ans is kinda volatile, I wouldn't recommend that).  To find the length of some data of unknown size, you can't use length() because its not necessarily zero terminated, and you shouldn't use it anyway since its a slow routine and you already know the pointers are static.  Instead you can just subtract the start from the end of the data pointer.

:[Str1]->Str1
:[]->Str1E
:Copy(Str1,L1,Str1E-Str1)


That will be great in Sprite Editors which give us the HEX code in Str1, we will then absorb it and save it as a program-variable.

Does Str1E-Str1 optimize to the actual number of bytes?

I was considering doing this a while ago, but I had to delete everything off my calc. Irritating test, and when i got back home my computer crashed and has yet to be fixed, and I had to find number values for everything, and unfortunately no one at my school has Axe :'(

Yeah, something like that. But I'm really only talking about for a 'public' release.  The odds of having less than 15ish bytes left on your calculator is probably very rare.  Any triple digit of bytes is rare for me at least.  If you're just doing this to quickly test out the features or to generate a file like from a map editor then you really don't need the error checking since you're aware of the problem and know how to avoid it.  Its only if other people use your program that you would want to check for errors.
Ah, right, what if the programmer checks how much RAM is left prior the game execution and exit if it's too low, though?
In case you are wondering where I went, I left Omni back in 2015 to form CodeWalrus due to various reasons explained back then, but I stopped calc dev in 2016 and am now mostly active on the CW Discord server at https://discord.gg/cuZcfcF

yeah i didn't include error checking because i would hope that people have at least 10 bytes to spare on their calculator. that is neat though, absorbing other variables directly into your program. why are you taking it out next version?
