I was just wondering how you organize your(s) calculator-programming-related folder(s) in your computer.

I have a big Texas folder with all inside, I decided to tree it for you:

What about you?

In response to the recent news that the NSpire OS 3.0 can be programmed using Lua, a new subforum was created aimed at Lua Language.

I'd like to know who of you know Lua, like me I learnt Lua a few months ago, but haven't coded a lot of programs, it was more just learning.

I'm participating in Informatic Olympiads and the winners get to go to Canada for IOIs. USACO winners also go to IOIs.

Is there a chance that if I win I can meet any of you?

I have a request guys, attached is an image I'd like the white part to be removed so that it is nothing (transparent) and it has no background so it will go fine in any colour.

Thanks, if you could also tell me how to do that

I tried a rubber in Paint.NET but it's hard to control it, even with anti-aliasing enabled.

I have this code:

;Program made by: David Gomes

.nolist
#include "ti83plus.inc"
.list
   .org userMem-2
   .db $BB,$6D
Init:


    b_call(_ClrLCDFull)
        myVar .equ 60
ld a,myVar
ld h,0
ld l,a
b_call(_DispHL)
b_call(_GetKey)
    b_call(_ClrLCDFull)
res 5,(iy+0)             ; Disables 'Done' message
    ld    hl, 0
    ld    (PenCol), hl
    ld    hl, msg
    b_call(_PutS)            ; Display the text
    b_call(_NewLine)
    ret

msg:
    .db "Hello world!", 0
.end
.end
When compiling I get this:

Pass one...
myfile.z80:11: warning: Suggest remove extra parentheses around argument
myfile.z80:12: error: Can't recognize 'myVar' as an instruction or macro
myfile.z80:16: warning: Suggest remove extra parentheses around argument
myfile.z80:17: warning: Suggest remove extra parentheses around argument
myfile.z80:18: warning: Suggest remove extra parentheses around argument
myfile.z80:23: warning: Suggest remove extra parentheses around argument
myfile.z80:24: warning: Suggest remove extra parentheses around argument
Pass two...
myfile.z80:13: error: 'myVar' isn't a macro or label
Done

It's supposed to display the number 60 and then after a keypress display "Hello World!". What am I doing wrong with myVar here?

Even if most of you have seen this sequence before, here it is, good luck deciphring it and getting the next element (it's infinite)

1
11
21
1211
111221
312211
12112221
1112213211

 

I was just in the mood to create an Axe GUI library and I thought "Why not?".

So it's not really a library since I use subroutines to create frames, buttons and dialogs.

So that you can have an idea of how this works, take a look at the code to draw the ABOUT button you can see in the demo:

sub(DB,40,42,30,10
Text(46,44,"ABOUT
As simple as that!

Let's take a look at its event when pressed:

If getKey(54)
[80C0E0F0F8F0B818->O
If X>40 and (X<70 and (Y>42 and (Y<52
sub(DD,"ABOUT","PROGRAM MADE","BY DAVID","GOMES"
Repeat getKey
End
End
...
End


So you have just learnt the two Drawing subroutines, DD (draw dialog) and DB (draw button).

There is not a DF (draw frame) yet, I am tidying it up to make it all a subroutine, but when finished it'll work like this:

sub(DF,"TITLE",1,0
The 1 (which could be a 0) is for X button or no X button to close the frame.
The 0 (which could be a 1) is for allow [CLEAR] to exit or don't allow [CLEAR] to exit.

This is just a demo, but I hope the library can have some uses I'll be making a few more Drawing Routines for other kinds of buttons, listboxes, etc. Not sure of how to make a textbox though.

Probably they can be in separate files (the routines) instead of being in the same program as the main program.

What do you think?
