If you really need line clipping, you can use this 449 byte routine (not including the subroutines used).
The routine uses the full signed 16-bits of each parameter, however it fails for large |x2-x1| and/or large |y2-y1| due to overflow
Code: [Select]
:Lbl LineC
:If r4<<r2
:r1->r5:r3->r1:r5->r3
:r2->r6:r4->r2:r6->r4
:End
:ReturnIf r4<<0
:ReturnIf r2>=>=64
:r1-r3->r5
:r4-r2->r6
:If r2<<0
:r4*r5//r6+r3->r1:0->r2
:End
:If r4>=>=64
:r2-63*r5//r6+r1->r3:63->r4
:End
:If r3<<r1
:r1->r5:r3->r1:r5->r3
:r2->r6:r4->r2:r6->r4
:End
:ReturnIf r3<<0
:ReturnIf r1>=>=96
:r2-r4->r5
:r3-r1->r6
:If r1<<0
:r3*r5//r6+r4->r2:0->r1
:End
:If r3>=>=96
:r1-95*r5//r6+r2->r4:95->r3
:End
:Line(r1,r2,r3,r4)
:Return

request: Rect(X,Y,#, -#)
We must not let that suggestion die!
A better one though:
Rect(X1,Y1,X2,Y2,Filled/Not filled/Filled w border/Not filled w border)

Since Axe is about optimization for both speed and size, would it be better to have the compiler have 4 different commands that compile 4 different ways instead of having a bunch of code that potentially will not be executed, depending on what your doing ? (Of course this then becomes a trade of between program optimization and compiler optimization, which should be smaller ?)

Not that I'm an actual Axe programmer worthy of making suggestions, but I'd like to be in the future :)

First post doesn't necessarily mean someone's new. I myself posted for the first time ever on a forum after over 2 years of calc programming.

Yeah, I actually started calc programming 6 years ago.
I didn't even know there was a calc programming community until I found revsoft 2 years later.

Same for me -- I'd been coding for two years before I found these forums, but I eventually found my way here eventually after getting to TI|BD from a Google search.

You can introduce yourself to tell us more about you, jacobly. Welcome to Omnimaga!

Ah I see. I personally started in 2001 but started posting on forums in 2003. I quit programming in 2010, though. I hope your interest for Axe programming remains high for a while!

I started a long time ago as well.
But that aside:

Definitely a great idea for an Axiom.  Remember the whole reason Quigibo added the axiom system in the first place was so that he wouldn't have to run around adding in all these more specific features.

Ok I got a good request that should be very easy...

How about we could be able to define constants with this  'number' -> x1

That would replace all occurrences of x1 with the number we had told it to be.  That way we wouldn't have to change every value we wanted to change, and still have the speed increase of not having a variable.

You can already do that. Just do something like 1337→°Const, and now °Const is a constant that equals 1337 for the rest of your program.

It's very likely that this has already been requested, but I'm not about to scan all 531 pages of feature requests. The concept of returning a value would be useful. Since there is no multithreading, you could designate some free memory to serve as a return value store.

Example (substituting the address of the return value memory with `R`):
sub(STUFF, 1, 2) -> A
Disp A>Dec
Lbl STUFF
Return r1*2+(r2*2)

would be read as:
sub(STUFF, 1, 2)
R -> A
Disp A>Dec
Lbl STUFF
r1*2+(r2*2) -> R
Return

It just seems strange to me to have lambdas but not return values.

Hi adrusi and welcome to Omnimaga! The thing is that the last calculated value is always returned for the next operation; that's why a command like
Code: [Select]
:A+1→Bcan be broken into
Code: [Select]
:A
:+1
:→Bbecause at each step, the last calculated value (stored in an assembly register called HL) is used. So you could change your code to
Code: [Select]
:r1*2+(r2*2)
:Returnand sub(STUFF,1,2)→A would work.
