What should the OFFSCRIPT variable look like (in hex) if you want it to tell the calc to first unarchive, then run a program named "OFFBY1" on startup, then rearchive it? If you can't un/re archive the program using the appvar, then just to run it.
Something like this?
Code:
I haven't tested this yet, though.
Code:
.org $8001
Start:
ld hl,ProgName
rst 20h
b_call(_ChkFindSym)
jr c,NotFound
push af
ld a,b
or a
jr z,ArchiveVar
ret nz
ArchiveVar:
pop af
b_call(_ArchiveVar) ;archives any variable
ret
NotFound:
;stuff
ret
ProgName:
.db ProgObj,"OFFBY1",0 I haven't tested this yet, though.
Oh, then I think you can replace b_call(_ArchiveVar) with b_call(_ArcUnarc) and load the program name to OP1 again before the bcall.

Correct, that will work. I notice you push af, then ret nz, which is not a good thing.

My pleasure. It's a trivial fix, of course, let's leave it as an exercise to the (reader|ACagliano).

Ok, here is what I have:
Code:
The objective is to simply create OFFSCRPT.
Edit: Forgot to copy the actual data TO appvar.
Code:
.nolist
#include "ti83plus.inc"
#include "dcs7.inc"
.list
.org progstart
ld hl, AppVarObj
rst 20h
ld hl,AppVarObj-AppVarCode
bcall(_CreateAppVar)
ld hl, AppVarCode
ld bc,AppVarObj-AppVarCode
ldir
DoneCheck:
ld hl, AppVarObj
rst 20h
bcall(_ChkFindSym)
jr c, notOK
ret
notOK:
ld a, 0
ld (CurCol),a
ld a,0
ld (CurRow),b
ld hl, TextError
bcall(_PutS)
ret
AppVarCode:
.org $8001
bit 4, (iy + 8)
ret nz ;apd
ld hl, progName
rst 20h
bcall(_ChkFindSym)
ld a,b
or a
call nz, UnArchive
bcall(_executePrgm)
call UnArchive
ret
UnArchive:
ld hl, progName
rst 20h
bcall(_ArcUnarc)
ld hl, progName
rst 20h
ret
progName:
.db protProgObj, "OFFBY1", 0
AppVarObj:
.db AppVarObj,"OFFSCRPT"
TextError:
.db "Error!",0
.end
ENDThe objective is to simply create OFFSCRPT.

You would want to use .relocate $8001 instead of .org $8001. Also, you may want to look through this thread.
Ok. Using what I read, I made some edits:
Code:
Code:
.nolist
#include "ti83plus.inc"
#include "dcs7.inc"
.list
_ExecutePrgm .equ 4E7Ch
.org progstart
ld hl, AppVar
rst 20h
ld hl,AppVar-AppVarCode
bcall(_CreateAppVar)
ld hl, AppVarCode
ld bc,AppVar-AppVarCode
ldir
DoneCheck:
ld hl, AppVar
rst 20h
bcall(_ChkFindSym)
jr c, notOK
set 1,(iy+33h)
ret
notOK:
ld hl, 0
ld (CurCol),hl
ld hl, TextError
bcall(_PutS)
ret
AppVarCode:
.relocate $8001
bit 4, (iy + 8)
ret nz ;apd
ld hl, progName
rst 20h
bcall(_ChkFindSym)
ld a,b
or a
call nz, UnArchive
bcall(_ExecutePrgm)
call UnArchive
ret
UnArchive:
ld hl, progName
rst 20h
bcall(_Arc_Unarc)
ld hl, progName
rst 20h
ret
progName:
.db protProgObj, "OFFBY1", 0
AppVar:
.db AppVarObj,"OFFSCRPT"
TextError:
.db "Error!",0
.end
END
I'm glad you corrected the entertaininly-incorrect "AppVarObj: / .db AppVarObj,"OFFSCRPT". Comments:
1) You need to ChkFindSym at the very beginning, and not CreateAppvar if it already exists
2) Check the c/nc flag after CreateAppVar! Don't blindly copy if the create failed.
3) There's no point ChkFindSym'ing it after the create and copy, imho, as in the notOK subroutine

I started swearing at your dcs_sdk compiler at this point, for about five minutes, before realizing what was epically wrong with that.

Done!

I don't do it in that routine, do I?
