[Axiom] Run (Un/Archived) External Assembly Programs
« on: March 06, 2012, 02:52:08 am »
I thought that some Axe programmers would find it useful to be able to run archived programs. Also, the Asm( sequence I posted to run programs in RAM will leak memory if the program you call throws an error. So I wrote an Axiom that lets you run other assembly/Axe programs and fixes memory leak issues. If you want, there's even a provision in there that lets you prevent your subprograms from being run from anything other than this Axiom, in case they do nothing useful on their own. Additionally, it also lets you catch errors that the OS may throw; that is, it lets you prevent that ERR: screen from showing up. The attached ZIP file contains the Axiom, its source code, and all the documentation. I'm a little afraid that the part of the documentation about error handlers is a little unclear, so if you're confused, feel free to ask questions.

Quigibo and Runer112: Feel free to optimize this---I'm sure it can be---and put it in Axe.


Here's an example. Let's say you have a fancy intro screen that's very large. You want it to run if the user has it---regardless of whether it's archived or in RAM---, but you want your program silently to skip running the intro screen if it doesn't exist. Just put this code in the main program:
Code: [Select]
:AppOnErr(LSKIP)
:RunPrgm("prgmINTRO")
:AppOffErr
:Lbl SKIP
:Your program continues here

Ah, this would make a great Axiom, and would help out a lot with a project like XDE (If it wasn't dead :P)
Completed Projects:
   >> Spacky Emprise   >> Spacky 2 - Beta   >> Fantastic Sam
   >> An Exercise In Futility   >> GeoCore

In Medias Res - Contest Entry

Talk to me if you need help with Axe coding.


Spoiler For Bragging Rights:
Not much yet, hopefully this section will grow soon with time (and more contests)

What do you mean, "would"? It is an Axiom.

It works perfect for me and displays my own errors and everything, except when I exit the program, it displays the errors that the OS didn't show when the program ran. Is that normal? It's annoying.

Again, there is no better place to put this.

I'm having the same problem, am I not restoring something correctly?

That's . . . odd. Can you give me the simplest program that demonstrates the problem? Does running Asm(FDCB09A6 before quitting fix the problem?

Here you go...
PROGRAM:RUN
.PRGM
Axiom(RUNPRGM)
[prgmBASIC]->A
[00]
"prgm*TEMP"->Str1
GetCalc(Str1,length(A))->B
Copy(A,B,{B-2}r
AppOnErr(lERR)
Str1:Asm(E7FDCB08CEEF9B4AFDCB088E)
AppOffErr
Lbl ERR
Asm(FDCB09A6)

PRGM:BASIC
595*,-5-*-5

when run it gives ERR:SYNTAX

Sorry for any weird words I had to fight spellchecker for each word :P

Asm(FDCB09A6) just attempts to reset the ERR:BREAK flag. Which isn't happening here.

The Axiom is intended for running external assembly programs. Does the issue with error messages only happen when you run BASIC programs? It's possible the error message isn't being cleaned up properly. From what I read in TI's SDK, you don't need to zero errNo after catching an error. But maybe I misread. Perhaps Asm(AF32DD86) will fix that.

Oddly enough, the error fixed itself.
I added some code to my main program. (I think it was a DelVar) and the errors stopped appering...
 ???

That's usually not a good sign. It tends to mean you have (or had) latent bugs. Definitely check for memory leaks and signs of data corruption.

I wouldn't be surprised.
I am using it in a program that uses a homescreen hook, and with a lot of hex codes that I don't really understand.
I don't have a way of converting hex to asm commands. (If I did it would probably easier to fix...)

Anyway I look at it RunPrgm is still vital to a good number of my projects!
Thanks for making it!  :thumbsup:
