It is not possible to arbitrarily break a program from asm without using interrupts and special exit code.  BASIC is interpreted so that's why it can break anywhere.

Luckily however, the security is taken care of by Axe Parser itself.  It will give you the option of automatically archiving all the RAM including your source code before testing your program so that if it crashes, you have everything backed up and you don't lose anything.  I will start working on these features in a few weeks probably.

Thanks!  I think that would work too. :D

Oh that's too bad.  Out of curiosity, what happens if you try to break out of the program while within a sub?  Does it just crash then?

Apparently you can't break at all, so it doesn't matter. But Quigibo, if you save the stack pointer somewhere at the beginning of execution, it should be no problem (this method is used quite a bit in asm programs iirc)

So what would happen if you broke out of the program but didn't restore the stack pointer?

Yes I use this too.  But it would still require a special interrupt setup and interrupt routine which might prevent custom interrupts.  Regardless, I think I'll just worry about this later and focus on the more important stuff for now.

It would return out of the subroutine without finishing it causing unknown consequences.  It would not exit the program either.

Sorry to double post, but I've just started to add the "Output()" feature and I'd like to get some feedback on it.

I know that native BASIC uses Output(y,x) but I much prefer the form of Ouput(x,y).  Should I keep it the old way to less confuse people transitioning from BASIC to Axe, or should I change it to (x,y) so that its more consistent with "Text(" "Pt-On(" and the other drawing commands?

I think you should keep the old way, but start counting at 0 instead of 1.

Also, I think Text() is also (y,x) along with pixel-on/off/change/check.
It's only line(), Pt-On/Off that's (x,y)
I'll rather have it (y,x), since I got so used to it

Spoiler For funny life mathematics:
1. ROMANCE MATHEMATICS
Smart man + smart woman = romance
Smart man + dumb woman = affair
Dumb man + smart woman = marriage
Dumb man + dumb woman = pregnancy
2. OFFICE ARITHMETIC
Smart boss + smart employee = profit
Smart boss + dumb employee = production
Dumb boss + smart employee = promotion
Dumb boss + dumb employee = overtime
3. SHOPPING MATH
A man will pay $2 for a $1 item he needs.
A woman will pay $1 for a $2 item that she doesn't need.
4. GENERAL EQUATIONS & STATISTICS
A woman worries about the future until she gets a husband.
A man never worries about the future until he gets a wife.
A successful man is one who makes more money than his wife can spend.
A successful woman is one who can find such a man.
5. HAPPINESS
To be happy with a man, you must understand him a lot and love him a little.
To be happy with a woman, you must love her a lot and not try to understand her at all.
6. LONGEVITY
Married men live longer than single men do, but married men are a lot more willing to die.
7. PROPENSITY TO CHANGE
A woman marries a man expecting he will change, but he doesn't.
A man marries a woman expecting that she won't change, and she does.
8. DISCUSSION TECHNIQUE
A woman has the last word in any argument.
Anything a man says after that is the beginning of a new argument.

Girls = Time * Money (Girls are a combination of time and money)
Time = Money (Time is money)
Girls = Money squared (So, girls are money squared)
Money = sqrt(Evil) (Money is also the root of all evil)
Girls = sqrt(Evil) squared (So, girls are the root of all evil squared)
Girls = Evil (Thus, girls are evil)
*Girls=Evil credit goes to Compynerd255*

I personally would suggest x,y and starting with 0, to be more consistent with every other functions. I myself easily get confused with the BASIC output cuz I am so used to x being first in graphical functions except Text x.x

It would also help people get more used to standards

Just hook the program interrupt and the break interrupt. Not hard, I think. And yes, essential features first.
