aeTIos : of course I don't call it in all my programs ! If I don't need it, I don't include it.
It's a library for DCS's graphics, so when I use it, I generally use at least :

•Get/Display cursor
•Display Window

And often :
•Button
•Cursor on a Rect

I my last program usind it (Fritzing on calc), I use almost all functions !

But with a real library, Axe compiles only the code of funcs which are called, doesn't it ?

Yes, I know.
With including AXELIB7 in source code, compiled prgm has 1.2kb more. (It's the tall of compiled library - but compiled library is definitely not useful ^^ )
The source code is just 800 byte.

How to make an Axe/ASM library ? o_O

It will be very great if Quigibo can write all my functions in Axe 1.0.0 ...
It will take less place, no ?

aeTIos : If I include it at the end, will it be better ?

PS: does someone know how many space will take AxeParser 1.0.0 ?

I don't exactly understand what ZippyDee said ...
I have prgmAXELIB7, and in my axe source code, I write at the top:
.PROGRAM SomeThing
#Icon(---)
[---]->GDB1
prgmAXELIB7
.code

In each program, I include it but axe parser includes all code of AXELIB7, so the compiled prgm has something like 1200 bytes more ... -_-

When you connect a calc to the serial port of an arduino, what does it do ?

I had two ideas :
• coffe browser (developpement stopped, see my sig)
• radiocommanded car with video

How do you find the piano ?
I'm trying interrupts, with what ralphdspam said.

EDIT: I've no headphones here ... -_-'
