Actually, even though the bottom is cleaner and easier to read, the top is still more optimized I think.  That's because he doesn't need to store to temporary variables to call the subroutine, the original subroutine was specifically made to only draw points from the X,Y variables which is fine for his use.

EDIT: And yes, r1-r6 work just like normal variables.  Anywhere you can use a letter A-Theta you can also use r1-r6, including for loops and storing to them.

But they look very convenient for temporary uses like in functions and loops.
That really should help readability of code. Nice add!

Another question about parameters: Can we use constants as parameters in addition to variables? Something like:
Code: [Select]
Sub(SE,X,Y,14or just
Code: [Select]
Sub(BL,9,30,2to store those numbers to the r1-r6? Also, since it's r1-r6, does that mean we can send up to 6 to the sub?

Not only can you use constants AND variables, you can us ANY expression including other subroutines and asm code.   If you want, you can call something with sub(L,X+2,Str-X*2^5-A,sign{'A'+sub(B)-{L1}}).  Go crazy.

And yes, you can have up to 6 arguments and as few as 0.  Only the temporary variables than need to be passed actually get updated.  You can have subroutines that take a variable number of arguments too.  Like if you make the first parameter be "number of arguments" then you can have the same subroutine function multiple ways with different numbers of arguments.

Lol

Try to avoid abuse of them, though, because many french people visits this board and in our netiquette, all caps are considered as yelling, unlike on english boards, where they are considered as emphasis, so some people could take them as rude.

And nemo I was kidding with that code :P. It just basically meant to not go WAY too overboard either :P

Just backup first, of course :P (I, myself, managed to forget that part, once, before testing a little program, even if I told myself I must backup first)

if axe supported floating point, i would make this the most epic quadratic solver known to man. because i'm lacking in that department, this will be.. interesting.

lol

Since this project started, I wished that floating point numbers support would only come after the first Axe program is uploaded on ticalc.org. I still have some bad memories of when I saw the very first ever BBC Basic language upload there. :P

Anyway back on topic, I assume the r1 through r6 stuff can be used inside sub() commands too, right? (such as sub(AB,r6,C)
