I understand, I figured either would work but I get why this is better. And ya, thanks to ztrumpet I am lol. How many are there?

Ok, sounds good. I wasn't sure where to post this. I just posted it where it says you can "get or give calculator help..." Works either way though, thank you

Oh ok, well that is pretty lame haha. So the black boxed equal sign is as close as you can get then?
As for downloading I get it. I think I did it wrong then because those are the directions. I shall try, thanks DJ 3051

Oh ok. So this is speed optimization, not size. I get it Thanks.

I know nothing about the AxeParser language, yet, but why would more divisions be faster? It just doesn't make sense to me

Ah ok. Thanks, I'll check that out.
Edit: Unfortunetly, I don't think there is a way to get files from UTI off the "Project Releases" topic. Also, is there any that has a black box to choose? I haven't seen one 3054

That's a good idea. Thanks guys
I didn't know Weregoose had one, where can you find his? 3055

@ztrumpet
I changed it. But I'm gonna leave it on UTI because I'm just to lazy to go back and do it again Plus we have mentioned it there. @Geekboy1011 Thanks, i really hope so. 3056
TI-BASIC / Movement Code Explanations« on: March 07, 2010, 12:05:00 am »
The other day Ztrumpet gave some TI-BASIC code for moving something on the homescreen over at United-TI. I went and fully explained both these sets of code in great detail (the first was more detailed than the second). I'm not sure how many people will find this usefull but if you're new to programming it might help.
I will be working from the top line to the bottom line. Also, please let me know if anything is incorrect, I will change it. This is the first example he gave: Code: [Select] 8→A 8→A: This is pretty easy. You are storing a value of 8 to the variable A. ClrHome: Again, a pretty easy one. This just erases all the data on the homescreen. So say you have a bunch of equations and answers there from math and then you run that all of it will disappear. Code: [Select] Before ClrHome: Repeat K=105: Well like ztrumpet said earlier Repeat loops are basically loops ran until the condition is met (post-test apparently). Post-test, from what I understand, basically means that it will check to see if the statement is true at the end of the loop, instead of first. As for the next part of that, the K=105, I think it was basically covered. But as you saw later in the code getkey is getting stored to the variable K. This means that when [Enter] is pressed (the key code for [Enter] is 105 (without using other things, but that's more advanced stuff I don't even understand currently)) the loop will finish and finish the program (since nothing is after the loop). Output(1,A,"*: So Output( was also kind of covered. Output( has three basic components to it: the row number, column number, and the thing to be displayed (in that order). For example: Code: [Select] The program: The Output( here is basically placing the word "HELLO" the fourth row down and starting the "H" at the seventh column. If you didn't know the homescreen of the calculator is on a axis from 1-16 horizontally and 1-8 vertically (the graph screen is something like 0-94 horizontally and 0-62 vertically, I think). Code: [Select] _1234567890123456 //The "0123456" after the "9" stand for 10, 11, 12, 13, 14, 15, and 16. Make sense? Ok, back to the Output(1,A,"* in the program. This line basically just displays a * into row one and in column A. Repeat Ans: This basically does what ztrumpet said. It stays in this loop until you press any key. The reason for this, though, is that a key press is a form of Ans. An example to show this would be: Code: [Select] PROGRAM:TEST getKey→K: This is what triggers the loop it is nested in. When you press a key the getKey command will capture this code (hence it being called getKey haha) and store it into Ans AND the variable K. This is because it is the answer from getKey but getKey is storing it's information to the variable K. You technically don't need the ...→K part of this, but you will run slower if you don't. End: This basically just lets the program know that is the end of the loop. End commands are needed at the end of each type of loop (whether it is While, For(, or Repeat). You need it at the end of other things but I'm not covering that now. Sorry. Output(1,A,"_: This is basically like the other Output( command, just instead of displaying a * it displays space. The point of this one though is that it erases the trail that would normally be there. Quick recap: 1 is the row number, A is the column number (this changes with the next line), and a space is what is being displayed. A+(Ans=26 and A<16)-(Ans=24 and A>1→A: Well this one is going to be a doozy haha. I'm going to try to split this up. -(Ans=26 and A<16) and (Ans=24 and A>1: So this is definitely better explained here (Boolean Logic) and here (Piecewise Expressions). But I'll try to explain this some. Basically when you have a function that uses =, ≤, and anything else in the [2nd][MATH] menu (in both TEST and LOGIC list) you will return with either a 1 (meaning the statement is true) or 0 (meaning the statement is false). A quick program to show this is: Code: [Select] PROGRAM:TEST Essentially this means that the (Ans=26 and A<16) and (Ans=24 and A>1 can be replaced with "1's" and "0's" depending on which is true when. That covers that part. -The next part I'm going to explain is the individual parts (not the "1's" and "0's" aspect though). First, the Ans=24 and Ans=26 pieces. Basically Ans right here is the value of getKey or K because that was the last thing to be stored to it. Easy enough, right? The A>1 and A<16 are easy to understand too, I hope. A is the column number, as I have said, so this is making sure it remains above 1 but lower than 16. otherwise you will get a ERR:DOMAIN error (I'm pretty sure that is the correct error). The only part left of those commands is the and part. This is pretty self-explanitory. Basically you have to have both the conditions met (to obtain a 1 for an output) otherwise the whole condition will be a 0 output. -Finally, to put that all together. Depending which condition is made true ((Ans=26 and A<16) or (Ans=24 and A>1) you are adding or subtracting 1 (or 0 if neither are met). I am hoping I explained that line of code well enough. End: Finally, the last line of code haha. This one is simply ending the Repeat K=105 loop. I believe I covered all of the lines of code, also I hope I explained what they do and how they work thouroughly and correctly. Please let me know if I have made a mistake somewhere, I will fix it. As a final little thing, I will explain what each line of code does in the actual program just briefly. As a final recap. Code: [Select] 8→A //Stores a value of 8 to the variable "A." Here was the second example that I explained: Code: [Select] 8→A Ok, well like last time i will go line by line, but probably not into nearly as much detail. Lets start: 8→A: Pretty simple. You're storing a value of 8 to the variable A. ClrHome: This clears the homescreen of everything that is currently on it. For more detail look at my last explanation. Repeat Ans=105: This is the beginning of the a Repeat loop that is waiting for you to hit [ENTER] (since it's key code is 105). A+(Ans=26)-(Ans=24: Little trickier. A currently has a value of 8 (when the program is run) so when you hit the left or right arrow key (which will be stored in Ans because getKey is the last line of the loop) you will either add 1, -1, or 0 to A. This answer will now be stored to Ans which sets up the next line. Ans-16((Ans=17)-not(Ans→A: Even more tricky. This is the line that lets the * wrap around. Like I had said the new value of A has been stored to Ans in the last line. You are essentially adding either 16, -16, or 0 and then storing it to A. How this works is that it takes the value in Ans and if this value is equal to either 17 or 0 you are multiplying 16 by 1 or -1 (thanks to the Boolean Logic I explained earlier with conditions). The reason this works with zero though is because of the not( command. This essentially reverses the Boolean Logic and returns the opossite (true becomes false and false becomes true). Now, to be honest this doesn't make the most ammount of sense to me but I do know why it is used here. Using the not( command in this way lets you replace the statement Ans=0 (because they return the same answer). It's used as an optimization right here. Output(1,Ans,"*: This outputs a * into row one, Ans number of columns out. You can use Ans here because of the last line. You are storing the value of A to Ans because it is a math operation basically. Hope that makes sense. Repeat Ans: This starts a loop that waits for you to push a button. It does this because the value from getKey gets stored to Ans. End: Ends the Repeat Ans loop. As specified earlier (in the previous explanation) End's specify the end of code inside loops (or a few other things that require them). Output(1,A,"_: This displays a space into row one and in column A. The reason for this Output( is to erase the * that would normally trail behind. End: This ends the Repeat Ans=105 loop. This completes the code so if you hit [ENTER] it will end the program (since nothing is beyond the End). So, quick recap: Code: [Select] 8→A //Stores a value of 8 to the variable "A." I hope this helps anyone who had stuff to take away from this. Again, just thought some might like this. Enjoy 3057

Ya, I remember a program like that from a few years ago. I hate when you can't remember things like that haha. What programs do people use? (Just anyone, just curious to see what's out there.)
