Yes.  I mean, an appvar that contains the ASCII representation of a string.

How do you change a program into an appvar through CalcSys?

I don't remember. I just used that shell thing Cooliojazz posted in "Projects: Post and critique" a few days ago. Be careful, though, it's a bit buggy if you do something wrong, but it lets you change programs into appvars and unlock them. I think they need to be at least 5 char names, though

Otherwise there is Celtic III' by Iambian, but I do not know how.

I believe getcalc without size only tries to find the appvar. Returning a 0 if it doesn't exist.
Could be wrong tho.

Yeah, that's it.

Go to the VAT entry and change the ID.
I think it's documented in the zip file.

I looked in there. No documentation exists of this feature. Explain please?

Don't know exactly how to do it with CalcSys, but I believe there's one byte for each VAT entry (I think it's the first one counting backwards, called T) that designates what type of variable it is. Changing just that one byte will change whether the data is a program or an AppVar.

Tried it out on WabbitEmu. I changed the AppVar AxeData into a prgm just for the fun of it .

1. Go into CalcSys (duh).
2. Select 6. More.
3. Select 1. VAT.
4. Select 1. Prog/List VAT (which lists all the data for programs, AppVars, and lists).
5. Find AxeData. If it's not there, select 6. Next until you do find it.
6. Select it (by pressing the corresponding number key).
7. CalcSys will show you a screen full of information about the AppVar. Press ALPHA+[V] to edit its VAT entry.
8. Conveniently, the byte at T for AxeData is already pointed to for you. Just press ENTER to edit the byte and change it to 05 (ProgObj).
9. Press CLEAR twice to exit the app. AxeData should now be visible in the program menu (don't edit it).
10. Remember to undo all of it when you're done, or just delete the program AxeData.

Changing a program into an AppVar is the same, except you want to change the byte from 05 (ProgObj) to 15 (AppVarObj).

Do you know the address of that byte? And the numbers that you're allowed to change it to?

You can change the value to any of these hex numbers, except that most of them will probably mess up your calculator since the data takes different formats. Programs and AppVars can be exchanged fine since they have such similar data formats.
