I found this in the Commands.inc file of axe1.2.2a:
p_IntNe:
   .db 8
   xor   a
   sbc   hl,de
   jr   z,$+5
   ld   hl,1

I can't find the purpose of xor a.

Perhaps a command that draws a triangle with coordinates: (x1,y1),(x1,y2),(x2,y2)
And perhaps a command that creates a bit map of a random triangle,
which might be done by filling it completely and then erasing the edges by the previous proposed command.
I think this would be a great base for jobs like drawing skewed sprites (defined by 4 random points and a sprite).

also, i think I've found a smaller code for ee14 (if it isn't changed already).
now it takes 7 bytes, but it can be done with 6 bytes only too with as code:
xor a
add hl,hl
add hl,hl
ld h,a
rla
ld l,a

I thought I found a better way for ee15 too, but it seems the auto opts file was wrong about that.

Can the fill( function be auto opted when the byte it should fill with is a predetermined constant?
And can it be optimised even further if the size is less than 256?
I think it would look like this:
0<size<256:
bytesize: 7
ld b,*
ld(hl),*
inc hl
djnz -5

size>=256
bytesize: 15
xor a
ld bc,**
ld(hl),*
inc hl
djnz -5
ld b,255
dec c
cp c
jr z,-11

and I think the current code has a size of 18 bytes.
I don't know if the code I gave is as optimised as it can be (nor have I tested it yet), but it is smaller.

I've got 3 more things to ask.
1. I think I've found an optimisation for comparing an expression with a constant, to check whatever it is bigger or equal to it, or whatever it is smaller. This should be a start of it:
≥≥B should be the same (but larger) as -B<(32768-B) where I use 2 times a minus simple to substract, not to invert, and where 32768-B is being calculated at compile time, since b is a constant.
now, since <<B is the opposite, it should be the same as -B≥(32768-B)
This comprimises a few bytes, however, check whatever this may indeed be done first.
2. I'd like a function that makes a signed 2 byte value out of a 1 byte signed value.
I know this can be easily done by, for example, the following structure:
→Ae0?A+65380→A
and then A holds the value, but I'd like a more compact version of it that can be written in 1 function and only costs 4 bytes of space.
The assembly would look like this:
ld a,l
add a,a
sbc a,a
ld h,a
This would be a feature I would use all the time, because I save a lot of data, like speed, in a single byte, but need to add it to a double byte value, the position
3. It seems that the Disp command doesn't work very well if you have MATHPRINT turned on.
When trying to draw a number, it draws it kind of diagonally and it only draws the first character of strings.
This is at least what I've made up out of some tests.

Oh, so that's what the multi page feature means? being able to make apps larger than 16kb with axe.
I don't really understand what the complications are that come with multiple pages,
I tried to search, but found few information about it.
I would love to have the multi page feature, since I'm working on a big project,
not knowing I can't exceed 16kb and I've almost reached the limits (about 15.5kb).
also, could it be that there comes problems if I try to upload big axe made applications to my pc through ti connect?
for some reason he wouldn't download it, no matter what I did, while everything else was being uploaded perfectly.
it always throws up the error: packet length not valid

then that'll be the problem, I didn't use an I/O port, but the USB.
I'll try out the effect when I use the other port (at least if I find a cable for that).
Thanks!

I've got another 2 requests:
- making an option so that you can easily make screenshots of your game, I can't find any other way besides using emulators.
- the syntax +→ and -→ to add/substract an expression to/from a variable or position in memmory pointed to.
