I'm not sure if this is related to zStart either, but whenever the calc garbageCollects the calc starts screwing up...I've gotten "ERR:?" twice now and it likes to deposit junk tokens on the homescreen.

Feature request:

-Instead of having one app/program set on start-up, I'd like to be able to set several ones, in a particular order. That would also mean that you would have to change the way of setting them :-/

-Instead of being able to only set 10 programs/apps with ON+[one digit number], I think that would be great if we could have several digits available, digits that we input while the ON key is pressed

After reading my post, it sounds to me that I only asked impossible things

I just got another idea: maybe make it somehow possible to insert any hook and it is restored when ram is cleared. I don't know if that is possible..........

Another problem that is not a bug: in a basic program with Input, we can do 2nd Quit and the temporary program stays in RAM.

That sounds fixable.

But what would be cool would be damn! I forgot my feature request! :O
Just remembered! It's about the editing when archieved.
It works fine and all if you move the curser to the program and then hit enter, but if I press e.g. 8 it gives me error: archieved.

I know about that, but that is a mega pain to do. It also has the potential to make you end up opening the wrong program

That's not related to zStart, but try this. I wouldn't doubt that you are very close to having a non-booting calculator.

I've thought about that, it wouldn't be very difficult to do that by setting a program in that position that runs all the other programs. I might make one of those sometime.

Ok, but this one wouldn't be easy. It would require major rewrites of anything that involves the appvar, which is like 50% of the app. Then, I would have to completely change how the ON hooks work. I can tell you with certainty that this will not happen. But, do you actually use all 9 shortcuts?

In principle that's not hard, it's just the whole UI that would go along with it would be messy. Not to mention it takes up variable space in the appvar.

Maybe somehow like a mix between the omnicalc options menu and the listing of the apps

And it could launch apps too ? O.o That would be awesome

Yes I use all of them

Yeah, I knew it would be hard, but don't worry, some of the shortcuts I use are not important, and I can redefine them for something more important.

Yeah, I use that fairly often

[offtopic]So for the booting thing, would it be possible to fix it with Flashy or something?[/offtopic]

Hmm, that seems useful and doable

Would it just require finding the app page and jumping to 4080h?

Yeong · « **Reply #563 on:** November 20, 2011, 06:55:14 pm »

I think zstart already have that feature.

No. You have to parse the app's header to figure out where its executable code begins; the OS starts an app right after the last byte in the header. There is no need to pad the header to 80h bytes. Fortunately, the OS provides a BCALL that does all of this for you, ExecuteApp. This will probably leak RAM if called from within a RAM program unless you deallocate yourself first.

Incidentally, you can also put whatever you want in the datestamp signature field. Nothing ever checks that signature.

DrDnar · « **Reply #565 on:** November 21, 2011, 04:26:31 am »

Double post for an update: the following assembly program will execute the application named in Ans. This program never returns. Note that applications whose name is less than 8 characters are normally padded with spaces at the end.

This should go without saying, but don't run this from within a shell. (zStart doesn't count as a shell in this case.) It completely subverts the normal way that assembly programs are supposed to quit. Any assembly program can copy itself to scratch RAM and do ld hl, 9D95h \ ld de, (asm_prgm_size) \ b_call(_DelMem) \ b_call(_JForceCmdNoChar). This is what the below program does, except that instead of executing the internal homescreen app, it runs the app you've chosen. This is a horrible way to quit if you're running from within a shell.

Edit: Possible bug fixed due to incorrectly correct .org.

Source:

Code: [Select]

; ExecApp
; This assembly program transfers control to the application named in Ans.  This
; program never returns, unless the application does not exist, or you fail to
; specify a valid name.
; This can probably be improved quite a bit.  Do feel free to steal this source
; and use it in your own, more complete multi-program runner.

I just encountered a strange bug:
I was toggling back and forth between Radian and Degree modes, and after hitting [On] + [Sin] about three times, the calc froze, and RAM Cleared. I have no idea how this happened, though based on the timing I think interrupts were to blame.
I have a TI 84+SE running 2.43 with Axe, Omnicalc, and Zstart.

Hayleia · « **Reply #567 on:** November 25, 2011, 01:28:22 pm »

I have another bug (is that a bug ? because I like this one

):
When the calc hits a bug, it turns off, then Ram Clears when turning on.
BUT, if when turning on I keep [Clear] pressed, strange things happen:
-The prog that should run on Ram clears does not launch
-The contrast is not set off
-In fact, everything is like zStart is not installed (no hooks working)
-There is no program in the program Menu
-Launching an app causes crash, and to Ram Clear, and to get everything back to normal

(except if I keep [Clear] pressed again)

I've read a part of the readme and it says like everywhere a million times(

) that while rebooting and pressing [Clear] zStart won't be installed. So no, it isn't a bug.
