TEXT SCROLLING HELP ANYONE

[john massey]

I would like to have a scrolling program to use on the home screen.
My "musts" list is not very long.
1) Since this is going to be used by children it must be user friendly when used in the program. The child must be able to control the scrolling, somehow. It would "be nice" if the child could use the function keys at the top of the 84 to do this. Like "STOP" and "GO" buttons or "SLOWER" and "FASTER" buttons.
2) By whatever means it must not bifurcate text. We are having trouble with getting children to read let alone , deciphering a bifurcated word.
My "wants" list is long and is based on my limited capabilities.
1) I need to be able to load the application. If the available scrolling program does not have simple instructions, this old bird with limited memory, will need some hand holding☺
2) It would be nice if I could work in TI connect, check it out there and then install it there in the application. Doing all that in the calculator will not be fun but I can manage that.

How long are the words you are trying to use? are they all going to be in the program or inputed into a string Ill put my code into this post when i get home

I am working with some folks on the TI developers site. I, We are trying to get the code below running. The line of code that begins with B+ is where the trouble is. The compiler somehow does not like the = signs. But here is where we are now. I did not expect some much talented responses. If you want to think about something, nothing has been said about the scroller cutting up words. In the word processing world, it is called bifurcation. If nobody can figure how to prevent bifurcation, I will just half to put spaces in the code. Here is the code present version. I took out the comments out of the code. You can see the program on the developers site if you are not able to dope out what is going on.

"Hi there Today we are going to do some more math flash cards. Remember when your hand help super computer stops, that is your sign that it is waiting for you to do something, so you should press the enter key. The enter key is on the right hand side at the bottom of your super computer keyboard. You should remember that when you see the ? you need to decide on a value to solve the flash card problem. Then press the white keys and press enter. The super computer now waits for you to study the screen to see what has happened."→Str2
1→B
For(A,1,length(Str2)-16
Output(1,1,"sub(Str2,A,16
getKey→K
B+(k=24)-(K=26)->B
rand(B
End

I found your problem. The "rand(B" does not accept inputs less than 1. So the first time you push to the right, B goes to zero and does a domain error.

To fix this you could change it to:

B+(k=24)-(k=26)->B
(B=0)+B->B

This way if B=0, it adds 1, therefore making B=1.

the program as shown does not run as anticipated after I made the changes you suggested. The program runs but hangs up on the output line of code. The home screen shows sub( and the remainder of the line. The processor runs for a while. I can tell because those small dashes on the upper right side are running for a while. While I am not a programmer I would like to say that I think the quotation mark should not be there since the code beyond the quotation mark is code not text.

Yes definitely remove the quotation mark. I kind of just thought it was a typo.
