I need to double check it. There may be one issue. I directly edit the *Reserved* byte of the VAT for two programs, so calling the wrong address could cause issues. Other than that, idk.

It isn't supposed to write to flash. It is supposed to do all writing in the RAM. That's why I have no clue what the f*** just happened.

Progress Report
MAJOR ERROR IN MY PROGRAM THUS FAR. I COMPILED AND RAN IT AND THE FOLLOWING HAPPENED.
1. When I try to run or edit any program from the TI-OS program menu, I get Err: Undefined.
2. Axe Parser 0.4.4 throws an Err: Unknown Err.
3. CalcSys App crashes when I try to enter the Prog VAT.
Resolved by reinstalling the OS.

No. I realized what happened, actually. I used TI-Data Editor, which i think it doesnt have the u, v, and w characters separate from the tokens. So when I sent the file to calc, it switched them all.

The token swap on u, v, and w that becomes appv, grp, and var is happening within text strings as well, causing garbled text to appear in displays.
Version 0.4.4

I'm looking for some asm routines, for use with Axe's asm( command, to do the following:
1. Return a pointer to a dirty variable, the appvar BSets, so that I can copy it back to ROM
2. Install a link hook, that, at the completion of a link transfer, calls a program named BLINK, with the name of the program just received stored into a temporary appvar (only do this if the type received is a program). This is very optional.
3. Modify the BootCode so that, upon RAM clear, the archived program BSTART is always copied to the RAM program BINIT and the archived appvar BOFF is copied to the RAM appvar OFFSCRPT. (Is this even possible?)
4. What should OFFSCRPT look like to run BINIT on startup?
Edit: Forget about 2 and 3.

I'll test it out, but im worried, how many false alarms am i likely to get? I have never encountered a prank file, and im wondering how likely it is to give me a false positive.
I went for quote and accidentally hit "rate down". Then I rated it up. lol. As for your question, the virus definitions contain only severe stuff, so likely not many at all. I won't even catch all potential crash or feeze liable programs, but is designed to detect really dangerous stuff.

I should have a release of the partially complete software ready within a few days. A few features will definitely not be functional in this release, such as the RunProg Hook.
Anyone willing to alpha test, post so below.

Ok. Thank you.

Nope. Same thing. It always returns the e as the next folder, even when I create a new one to see if it changes.
I got it working.
Repeat sub(VNX)
should be
While sub(VNX)

It doesn't crash. That's a start. But it always returns the character e, no matter how many folders there are. Should it?

another question: is there any way to allocate more room for a variable you have accessed? so if i wanted to add a line onto a program, could i do it in axe by simply changing the size bytes of the variable in the VAT?
The only way I can think of is to do this: Assume an arbitrary program, prgmA "prgmA"->Str1
"appvATemp"->Str2
GetCalc(Str1)->P
{P-2}r->L
GetCalc(Str2,L)->V
Copy(P,V,L)
DelVar P
[# of bytes to add]->A
GetCalc(Str1,L+A)->P
Copy(V,P,L)
Return
.This should result in the same program, but with A zero data bytes added to it

Would this work:
:"%FLD["->Str1
:sub(VI)
:
:Goto A
:Repeat sub(VNX)
:Lbl A
:For(A,0,4)
:If {P+A-6}!={Str1+A}
:Goto B
:End
:End
:{P-1}->{L1}
:If {L1}>{L1+1}
:{L1}->{L1+1}
:End
:Lbl B
:End
:{L1}-48->L1
:Return
:
:.Initialize Vat pointer (using P as pointer)
:Lbl VI
:{E9830}r->P
:Return
:
:.Get Next Entry
:.Returns 1 if End of Vat or 0 otherwise
:Lbl VNX
:P-{P-6}-7->P>={E982E}r
:Return
:
:.Get current entry type
:Lbl VT
:{P}
:Return
:
:.Get Pointer to current name length
:Lbl VNL
:{P-6}
:Return
:
:.Get Pointer to current entry name (backwards)
:Lbl VN
:P-7
:ReturnL1 should hold the number of the highest folder, but my routine only should work for the first 10 folders. 
I wound up doing this... :.VATCHK
:"%FLD"->Str1 // That [ shouldn't be there. It was a representation on my part.
:sub(VI)
:0->{L1+1}
:
:Goto A
:Repeat sub(VNX)
:Lbl A
:For(A,0,4)
:If {P+A-6}!={Str1+A}
:Goto B
:End
:End
:{P-1}->{L1}
:If {L1}>{L1+1}
:{L1}->{L1+1}
:End
:Lbl B
:End
:{L1}-48->L1
:Return
:
:.Initialize Vat pointer (using P as pointer)
:Lbl VI
:{E9830}r->P
:Return
:
:.Get Next Entry
:.Returns 1 if End of Vat or 0 otherwise
:Lbl VNX
:P-{P-6}-7->P>={E982E}r
:Return
:
:.Get current entry type
:Lbl VT
:{P}
:Return
:
:.Get Pointer to current name length
:Lbl VNL
:{P-6}
:Return
:
:.Get Pointer to current entry name (backwards)
:Lbl VN
:P-7
:ReturnThat seems to work, but I'll do more extensive testing. Can you please try it as well. I want to make sure it works on more than just my calc. And try to create more DCS folders and see if it changes the result (it should). Thanks alot.

If I want to store something into an appvar pointed to by Z, but start at position 1 instead of position 0, would i do
A->Z+1
or A->{Z+1
A->{Z+1}
I know that now. But I'm saying that I can't get the routine to work. Here's what I'm trying to do: 1. Scan the VAT for all DCS folders (protected programs with the name %FLD[n], where n is a number. So, a DCS user with four folders on their calc would look like this:
prgm%FLD[1]
prgm%FLD[2]
prgm%FLD[3]
prgm%FLD[4]2. Figure out what the [n] value on the last folder program is (we'll call that value [n']) and create a name string that reads prgm%FLD[n'+1] For some reason my attempts keep crashing, so I would like to see if anyone else can help out. EDIT: The [n] value can be a number ranging (in hex) from 00-FF.

Yeah, I'm gonna wind up using the SortD command. But, I can't even get it to work. I keep RAM clearing. Can someone else give it a try and see what code they come up with.
