Hi folks, I have a problem... Currently, the variable sized Grammer font is incomplete (very much so) and I don't have the time or drive to finish it, so I am asking if folks could help me out.

What is needed:
-A font that is generally the same height for all characters (preferably >6 pixels tall) and with varying width.
-It should look good (not sure what I mean by that) and should have some variation in width (like a ! might be thinner than a W)
-It should map to the same chars as the TI-OS in the large font
-Any extra chars that are empty you can fill in with your own (I made little sprites for the 4x6 font)

To help you, I have made the attached on-calc tool (it has one slight update from the previous version of it).
Controls:

+ and - scroll through chars
arrows move the pen tool
6 makes the char wider
4 makes it thinner
2 makes it taller
8 makes it shorter
[Enter] will set a pixel
[Del] will delete a pixel
[2nd] will invert it
[Mode] will exit

Everything saves automatically when you press MODE or you cycle to another char!
When you have a font you like, upload the appvar here (and possibly a screenie) so we can check it out.

Thanks much!

I am working on my TIConcours entry (the SNAKE program) so I backed it up earlier. I sent it to the computer and that worked fine, so my entry now has a backup on the computer. However, I tried sending it to Wabbit so that I could look at it and at my calc while programming similar sections of code. That failed. So I tried sending another file. That worked! So then I tried resending the other program and again, it failed. So, I renamed it on my actual calc, resent it to my computer, and it sent it to Wabbit just fine.

Later, I decided to back it up from my TI-84+ (OS2.40) to my TI-84+SE (OS2.43). I got a Version error. So I tried sending another program. That worked just fine. I tried to send my snake program again and it failed.

So, what I am thinking is that the OS bugs out on the name. Unfortunately, I cannot give the last two bytes of my program name (it is an ID for the contest). However:

The name starts with Theta followed by SNAKE and then the ID number. This is a total of 8 bytes. Does anybody know what is wrong?

I am posting this because I figure it might be useful for anybody who wants to design a platformer in Grammer code. It also might serve as a decent example for pseudocode for others writing a similar engine *cough*

It features collision detection, grayscale, and gravity. For this example, use Enter to jump and left/right to move. Press clear to exit It draws a border, but otherwise leaves the screen untouched for your own obstacles.

I have in the past made some large Grammer programs that need to be debugged and a few others have needed to, as well. Because of this, a few months ago I added the solve(3 and solve(4 commands and I made Grammer able to output to OS vars. With these tools, you can make a powerful error catcher and handler.

I, like many, started programming in BASIC and one thing I liked to do when debugging was press ON and do Rcl <<offending var>>. So if I knew the issue was with the value in C, I would do Rcl C. But, Grammer uses its own variables, not OS vars, so you cannot do this! Instead, you can make Grammer copy the var to an OS var before exiting on an error! Here you go:
.0:Return
solve(3,Lbl "ERRHANDLE ;initiates the error handler
<<program code>>
Stop
.ERRHANDLE    ;label name is ERRHANDLE
→θ'           ;Ans will be initiated with the error code
C→iC          ;Stores C to the OS var C
solve(4,θ'    ;Lets Grammer continue with the regular error
End           ;Not really needed, since solve(4 will exit the parser
If you do not use solve(4, the program will not break. So if your error handler just has an End, the program will not break on its various errors (like on press). I made an example a while ago that brought up its own menu when ON was pressed or there was a memory error. It would give the user an option to exit, goto, or continue. That is an option you don't get in BASIC.

Okay folks, my trusty laptop of about two to three years has finally started to give out on me. I bought it new with a 1.6GHz processor, 3GB DDR2 RAM and 160GB hard drive space. That is still about all I need, but it has had quite a few problem in its short life:

After about a month, the screen started acting up and I finally took it apart (with no prior knowledge) and I found a component was over heating very easily. I broke the screen casing when I opened it (because I felt the warm spot and opened there), but since then, the screen has not acted up and has worked fine. About 9 months ago, either our dog or my little brother tripped on the charger cord and yanked it hard enough to break it, so the charger has been patched up and still doesn't work as well as it could (we used a charger tip from a 15 year old laptop that is very slightly too small). About 3 months ago, my battery finally gave out and no longer holds a charge longer than 10 to 15 minutes. Coupled with a faulty charger, I have learned to save my progress often. About two weeks ago, I started to notice that when saving to my hard drive, I would occasionally get a message saying that I could not save there (though I still have about 49 GB left). I am suspecting that my hard drive is having issues, now.

Here is what I want to do. I do not have very much money on hand, but I feel like I will need a new laptop. I want to try to take 2GB of the RAM I have on this laptop and put it in the new computer (laptop, most likely), so I am fine with a computer that doesn't have much RAM. A 160GB hard drive is more than enough for me as I mostly use my computer for programming and development as well as math and homework. Since 1.6GHz is pretty much outdated, I suspect that 2.6GHz is going to be what I should expect. The computer can be small or clunky, it does not matter. I figure that if it is small, it will last longer on a charge. I need to be able to access the internet for school and I will need to view .doc files and PDFs. I don't use my computer for games or most of the other garbage that comes with new computers preinstalled, so I don't need a bunch of features.

Does anybody have any tips, ideas, or help? I am currently searching for a computer with the following stats:
32- or 64-bit processor
I am okay with 1.6 GHz or better
120 GB hard drive or more
1 or 2GB RAM (if I am able to take 2 or 3 from this to put it elsewhere)

I still don't know how I will copy my hard drive data or remove the RAM and install it to the new computer.

Thanks much!

J'espere qu'il y aurait un tuto pour Grammer en français, donc j'ai decidé commencer ce projet, mais je ne parle pas français (bien).
   Bonjour, je m'appelle Zeda et j'ai fais le langage de programmation "Grammer." Premièrement, je ne parle pas français, donc la documentation peut-être mauvais (et, aussi, la grammaire). Le Grammer est une langage pour le TI-83+/84+/SE. Il y a un version qui est une programme ici, mais l'application a plus des fonctions, vitesse, et les autres fonctionnalités.

Qu'est-ce que Grammer? Grammer est une langage interprété.
Comment est-ce-que vous faites une programme? Utilisez l'editeur du TI-BASIC, mais le première ligne a besoin de le code:
.0:
Aussi, j'ajoute le token Return:
.0:Return
Comment est-ce que vous arrêter une programme? Le token Stop est le token que l'arrête.
   Je voudrais commencer le tuto avec une exemple. Vous pouvez "parler" avec le programme avec les fonctions et les tokens, mais la programme peut vous "parler", aussi. Donc, il y a des fonctions pour la calcul, entée, et sortie. Par exemple:
:.0:Return
:.LOOP            ;un label
:getKey→A         ;le pression sur la touche enregistrées dans le var A
:If A=0           ;Vérifie si A est zéro
:Goto Lbl "LOOP   ;va au le label "LOOP" s'il n'y a pas un pression de touche
:ClrDraw          ;efface l'écran
:Text('0,0,A      ;écrit le nombre en le var A dans l'écran
:DispGraph        ;affiche l'écran
:Stop             ;Arréte la programme
