I'm with ztrumpet on this one, custom Lists are almost always highscores or save files and i'm not sure if Strings should be deleted,  I know some games use them to store data.  I say just leave them out

The interesting now would be someone help me debug the TI-83 build. For the TI-83 there is few documentation on bcalls, but I will try to compare to TI-83+ to see what differences come out. Debugging on calculator and watch the entire bcall disassembly is a thing I won't do. Angry Maybe it is not worth to put on TI-83 nowadays.

I'll check tomorrow. You're probably using a 83+ only side-effect or assuming a register intact. Maybe a few extra push/pops will help?

I don't think the 83 has bcalls. There are only calls.

Oops, it is definitely that for starters. xD I saw TI-83 documentation so long ago... It is just question to change the bcall macro. (instead of rst, do a call)
Thanks mapar007 for offering help.
EDIT: It rocks in TI-83, yeah!EDIT2: I am curious about how easily I can assemble for TI-82, TI-73, TI-85 and TI-86. Just all the z80 calculators. I gotta to release my include files and edit WikiTI about this.

About lists I liked to know other lists like LRESID. Of course I will not mess others that are save games.
ANd most programs I see in forums use LA, LB, LC as temporary lists... But better keep this ones out, too. And sometimes appeared LL1 to LL9 in my calculator because of some TI program I checked. (CBL related, I think)

I remember back in 2003-04 there was something called the "TI-82, 83 and 83+ Unification FAQ", which was a guide by the TI French Team (TIFT) on porting games accross those models. It came pretty handy sometimes, but when the old TIFT site shutted down it took that guide away with them

Oh, I got a copy of that somehow, actually since many time ago. (http://www.ticalc.org/archives/files/fileinfo/369/36923.html) It has some good tips only today I added to WikiTI.
I wish I remembered that FAQ before... Thanks as always DJ. If someone remembers other similar topic, tell me.
But I think it is worth to write a topic about porting programs between calculator models. I plan to it even giving important routines to the port.
I will try out. I have 3 calculators models ports to go. ^^
Anyone here knows what are the most common shells in TI-82, TI-83, TI-85 and TI-86?
TI-83 is probably Ion. For TI-82 I think there is AShell and Crash but I only know their names.
For TI-85 and TI-86, I know even less. (there is Usgard shell?)
I will go into UTI topic about shells... It can have valuable information.

Ok, for TI-82 the bcalls needed are undocumented.

TI-86 variables format is different and you can have custom names even with matrices. Searching in VAT, more coding, few documentation, forget.
I tried on emulator.
TI-85 is similar with TI-86, so the same thing.

Well, next time I will waste time on something "less useless" (sounds funny). At least this gives me some experience to share in the WikiTI porting topic...

EDIT: The TI-83 version works with Venus shell but not with Ion... Some hint?

I uploaded to ticalc today, so it is still pending.

The TI-83 build of delete all variables is buggy and causes stability on TI-OS until it crashes. So it is not provided.
All the other builds work, though.

The first post will be edited with the new source code.
EDIT: done.
