ON break
« on: August 15, 2012, 02:03:17 pm »
Can anyone help me? I learned the basics of assembly language a couple days ago, and I'm building one of my first long term programs. I need to keep people from breaking with the on button (one of the reasons why I turned to asm!) ???

Isn't that automatically as the basic interpreter breaks on ON?
EDIT: And Axe programs also don't break on ON ;)

But the assembly program I've written can be broken by pressing On...

Yes, iirc the ON break is disabled automatically in asm.
But if you are familiar with BASIC I would strongly recommend you learn Axe Parser.

Actually, I have learned that a while ago, but I still wanted to use Assembly.

I think he means that his asm program breaks when he presses ON. If you don't use any OS routines (bcalls)(some will still work, but try it to be sure, and do that ON AN EMULATOR), then you can take full control by disabeling interrupts (the di instruction). This makes the CPU only run your code, so it won't do anything like breaking on ON, displaying the run indicator, etc. BUT it will also stop detecting keys when you don't use direct input. There should be a flag for this too, but I don't know which one.

ben_g is exactly on the point. But does that mean that I really can't use any B_CALLs?

are you by any chance testing with mirageOS? iirc that has break on ON interrupt.

I'm not using any shells. I'm just running it regularly.

hmm. Not totally sure but iirc bcall _getKey also breaks on ON. other than that i have no clue what could be causing this, never happened to me.

I am in fact using B_CALL _getKey. I wanted to use GetCSC, but I want to detect if any key was pressed, and testing for each and every key would be inconvenient.

B_CALL(_GetKey) returns with a = 0 when the ON key is pressed.  In order to use it again you need to res onInterrupt,(iy+onFlags).  Unfortunately, 2nd+ON can still exit the program during a B_CALL(_GetKey).  Fortunately, you can use B_CALL(_GetKeyRetOff) (which is what Axe uses) which returns kOff when 2nd+ON is pressed.  There might still be a link-port-related way to exit the program, but I don't know for sure.

the GetKeyRetOff on compilation says it isn't a label or macro. if I throw out that command, it still does not stop the on key breakage.

you can use B_Call($500B) instaed. It's the same.
