Its fun to screw around with this one, but if you do the wrong thing you can loose your RAM. You can make blue colored lines appear by switching on the custom font flag and then pressing y= when you exit calcsys!

~Jonathan Taylor

I just thought I shouldve said that it also crashes your calc when you do that, so be careful. I also somehow ended up with the 1st comment, btw :)

~Jonathan Taylor

This doesn't have much to do with the previous comment, but at the bottom of the board, nobody may ever get down there. I am programming on the 83+, and would like to know if there is a way to have more variables than just A-Z and the null sign. I have already used all of those and need more. Is it possible to assign a value to both a and A, or does case not matter, if it is, then I definetely will get Calcsys.

I've jsut finished a small pack of stack functions in Basic for the TI-82. The code should work just fine on the 83. I got the idea from a post on an old article here, but here's the progs and what they do. The stack is stored in L6, BTW.

CLSTK: Clears the stack
PH:Stores Ans to the top of the stack
PHN: Stores Ans to the Nth slot in the stack (doesn't overwrite anything)
PK: Stores the top slot of the stack to Ans
PKN: Stores the Nth slot of the stack to Ans
PP: Stores the top of the stack to Ans, then deletes it from the stack
PPN: Stores the Nth slot of the stack to Ans, then deletes all slots down to (& including) the Nth.

I don't have a graph-link yet, I borrow the one from my AP Cal 1 teacher when I need it. I can e-mail you the files (I'm going to post them sometime soon, if there's any interest) or if you want more info, email me at bcbates@cafes.net.

Oops. Hit the post button too soon. A few more notes about the stack function stuff.
1) The code should work just fine on the 83/83+
2) Using a list as a stack lets you have 99 variables (more on the other calcs, but 99 on the 82/83/83+, I think)
3) The only trouble is that you've got to keep track of where in the stack you put a certain variable...

An example in code:
:3+5 // 8 is now in the Ans var
:prgmPH // calling prgmPH pushes Ans to the stack
...
other operations, not messing w/ the stack
...
:prgmPK // calling prgmPK peeks the top of the stack to Ans
:Ans->X
:Disp "The answer is: ",X
:Stop

Any other usage ideas would be welcome, also optimization stuff, I think I've got them as small as possible, but I never know...

or besides the program the guy above me is making, you could store them into lists yourself..
it works like regular variables
code examples....
Ans->L1(1)
L1(1)*5->L2(4)
...
you can do anything you want with list variables.. they are exactly the same as regular variables.. and on the 83 and 83+ i believe that using this method will give you as many variables as you want or as many variables as the mem can handle

cool, thanks, my new game should come out sometime in the new year then hopefully, I am working on re-writing the code.

How do you make blue colored lines appear when the TI calc's pixel display's can only have varying shades of gray?

the contrast appears blue when set at the highest possible level...

The TI's screen will display blue when the contrast is all the way up and a pixels are on.
TI82's screen is blue already, as is TI85's.

You can get bright blue horizontal lines (different that what it looks like with the contrast all the way up) (some people claim green or red also) by messing with some of the lcd controller values. However, you can't turn just individual pixels to that colour, and you can't control the lines particularly well either.

hold up y'all - isn't it kinda dangerous to do that to your calc?

amicek

Nah. I highly doubt that you can do any even semi-permanent harm with Calcsys.

-Dan

Oh, so the FLASH ROM is reset when you reset your calculator?

amicek

No, the Flash rom is not reset when your calculator is reset (ram reset). But there is no way to write to the flash rom from calcsys, so you don't have to worry about corrupting your rom (if that was what you were referring to).

-Dan

So what if they made a mistake when they were coding this flash rom thing and it messed up your calc? Would there be anyway to restore the original FLASH settings?

amicek

"So what if they made a mistake when they were coding this flash rom thing and it messed up your calc? "

The point is it doesn't matter whether the app has hundreds of bugs or not. There is no way to change the flash rom from inside the application. There is no way you can "mess up your calc" and not be able to fix it with a simple ram clear, or taking out the batteries and putting them back in again.

-Dan

And what exactly do you mean by "incomprehensibly successful"?

hyperbole.

It means that you can't comprehend how successful it is. Why are you critisizing someone because they have a bigger vocabulary than you? I swear, there is more mudslinging on these discussion boards than any other I've participated in.

~Jonathan Taylor

Bryan just enjoys being annoying. Why else would he repeatedly comment on every nit-picky detail that everyone else is perfectally content to live with?

KnightRT

In case you didn't notice before, Nick has tried to use his "big vocabulary" before and messed up big-time on some news headlines. :) It was kinda funny.

Your offensive and spurious behavior makes me question your perspicacity.

--BlueCalx

LOL

~Jonathan Taylor

Actually it seems to be more like criticizing people because they use more and bigger words than they need to be. I personally think that some of the words Nick uses are unnecessary.

And yes, there can be quite a bit of bickering on the comment boards. I'm just so glad I'm not a big part of it. :)

When I first read that, it kinda sounded like "it's incomprehensible as to why the program was so successful." But what do I know?

That's what I thought too..

Ah ah ah.
I don't speak (write) English well.
But I understand that what is important, what Nick wanted to say, is that this program is very successful.
...oh that word is not the good one....
...oh he shouldn't use this one...
Yes, you're right. It's very (very very) important.
I can't understand how Nick can post such a message.
I think I will never come again on this site.

Seriously, couldn't you spend your time for something else?

I hope you understand what I mean

~Jonathan Taylor

he was being sarcastic, and for a non-english-native speaking person, i felt it went over quiet well.

(why do all foreigners like to write in short sentance/paragraphs and use lots of '...'?) :-)

...lol i dont know...
...I like them too...
...can you tell?...

Ok, I've understood: from now, I won't put any ....
With these ..., I tried to communicate something I didn't know how to say in English.
So foreigners like to use these ...? lol
I think short sentences are easyer.
And there is somthing funny with the message I'm writing now: I criticize those who write several messages on an uninteresting topic, and that's what I'm doing now.

J. Knusel

heh. sorta like me trying to form sentances in russian or german. short, and with hella gaps.
