2. Did anyone ever request a Axe( command?;

What would Axe( do? If you mean compiling a source from third-party programs, I suggested being able to do that in ASM :D Doing that for BASIC would require a parser hook, though.

3. Are there special getkeys for stuff like 2ND+MODE, or do we have to set a variable when 2ND is pressed?.

In ASM, there are several ways to get a key. There's low-level key reading, where you're reading the port directly, _GetCSC, where you're reading each key stroke (this is what Axe uses for getKey, so no 2ND+[MODE] combos), and _GetKey, where you're waiting for a key combo. In other words, _GetKey pauses the program until the next keystroke (no loop required), and if it's a 2ND or ALPHA, it sets the 2ND or ALPHA flag and waits for the next key. Kind of like in the TI-OS, basically.

There could be problems with implementing _GetKey in Axe, though. First of all it has problems of its own. If you do a bcall(_GetKey) in your program and the user presses 2ND+[OFF], the calculator turns off, quitting the program and causing you to lose RAM (since you didn't quit correctly). There are ways to get around that, either with more code or with the undocumented instruction.

If you want to try _GetKey for yourself, here's the hex for it: Asm(EF72496F2600)→K

If you want to try _GetKey without the 2ND+[OFF] thing: Asm(EF0B506F2600)→K

Axe( would compile and run (consecutively).

Thanks for the getKeys explanation, I'll probably do sth like that.

Code: [Select]
If getKey(54) and getKey(1)
. CODE
End
Which would require it to be simultaneous (what I want).

Quigibo: if possible can axe eventually have a Select/Switch case structure?  Y'know like in C/C++/Java/all that good stuffz

Maybe like:

Code: (POSSIBLE AXE SWITCH FORMAT) [Select]
Switch(X)
Case 1
1->Y
Case 2
3->Z
Case 5
X-Z->Y
Case Else
Sin(Cos(Sin(Cos(X))))->Y
End

So I'm guessing that because my idea was completely ignored it was a really bad one?

A switch statement for generating optimized assembly using vector tables would be very used, indeed.

We've had this much support for them before, and he hasn't added them.  Let's hope this time, the tide's changed! ^-^

XD

And a last-minute major request: Trinary operators! :D It would work great in Axe since it relies so heavily on HL. Not sure if it's too late to suggest something so big, though.

I would indeed like switch statements. Sometimes it's just easier to write code that way when the program can do many different things depending of the result of a variable, for example. (such as selecting magic that uses different code for each in a game)

Depending on the environment you are in it is currently possible to *sort of* do switch statements...or at least a more optimized form of what we do now (this is something Runer112 taught me by the way).
Code: [Select]
rand^9+1
!If -1
Do stuff
Return
End
!If -1
Do stuff
Return
End
!If -1
Do stuff
Return
End
and so forth...
You can replace the Returns with Goto's if you want. The important thing is that you have to get out of the whole code block after you're done otherwise it won't work.

You have to use Else!If in that case. Otherwise you could run multiple loops, depending on the returned value.

Not if you're returning or goto'ing somewhere else though :P

Edit for a completely unrelated subject: Can I bring up again a feature request for alternate steps for For() loops, the same way it is in BASIC?

You mean if QUigibo implements switch statements the source would be easier to read than this but the executable would be less optimized?
