For statement that skips numbers

[john massey]

If you had a normal "list" in a For statement such as For(I,1,16. and if you displayed the value of I for each loop it would display 1 2 3 4 5.... I have an idea which I am unable to get running. I have a list called OVER. I want to insert into OVER a"0" in places where I do not want to run code in my program. For example OVER might contain 1,0,3,0,5.. NOTE HERE

In the code after my For statement I and after the code I need from you, I have statements like this:

{6,32,8,9,10,3,12,16,6,4,42,7,8,6,7,11}→⌊FN002

Looking at NOTE HERE I want to use the "6" in ⌊FN002 but not the "32" because there is a "0" in OVER. Similarly the"8" but not the "9" The first thing I tried was:

If OVER(I)=0
I+1=I

That does not work.

[thepenguin77]

You were close on what to do.

If OVER(I)=0
End

Or to optimize:

If not(Over(I
End

This just loops if the number at I is 0.

[john massey]

I would like you to consider the fact that there is a lot of code after your end statement. It is my view that with the end statement the remaining code in the program will not run.

What say you?

[thepenguin77]

The End statement only gets acknowledged if the If statement is true. So if the If is not true it skips the End and runs the rest of your program.

[Graphmastur]

If you just don't want to acknowledge certain results, and since I know your project, and can therefore understand that, then you would need to do like thepenguin77 said, except instead of doing end after that, you need to do this:

For(I,1,16
If Over(I):Then
// Code to check goes here.
End

That way, if Over(I)=0, your code won't run.

I am at my daughters for christmas. Without my computer with TI connect. I will test and respond when I get home.

[Bhaliar]

I'd like to point out that an end code is merely there to stop conditionals. If the conditional is true and coded one way, it will do everything between the conditional and the End, then continue on. If not it goes to the end and continues.

[john massey]

I already have an "end" at the end of my program. Do I add another?

[Graphmastur]

Please show us your code.

[Weregoose]

A block which uses an End and is arbitrarily placed within the confines of another block would look like this:

:While A≠Z
:code goes here
:Repeat M=N
:code goes here
:End
:code goes here
:End

If you have an End-able section at the tail end of the inside of another section, then two adjacent End's are necessary:

:Repeat N=1
:code goes here
:For(X,1,2
:code goes here
:End
:End

:While I>10
:code goes here
:If K=21
:Then
:code goes here
:End
:End

Here is all the code in all it's glory. It skips. However when I input the answer for particular and answer with the correct answer The program responds telling me that I put in the wrong answer. Then the programs displays the same problem in the same location. This time I put in the same answer and the program tells me that was the correct answer.

So here is all the code with some comments. Fire away with questions.

I have found a bug in REDUE21. I do not know why or how to fix it.

I my initialization Program I did this:

ClrList ⌊JONL5
SetUpEditor ⌊JONL5

The bug centers around this block of code.

For(J,1,dim(⌊JONL4
If 3<⌊JONL4(J
J→⌊JONL5(1+dim(⌊JONL5
End

What it supposed to do is to index JONL5 whenever JONL4 is > three seconds.

Well L4 holds {3,4,4,3,2,3,3, 2,3,3,3,4}

If everything were working correctly JONL5 would hold {2 3 12} because these are the only values where JONL4 is > three seconds.

JONL5 holds{2,2,3,2,3,2,3,2,3,2,3,2,3,2,3,2,3,2,3,2,3,12}

You can see JONL5 got the first and last numbers correct. I have no idea where this other stuff comes from.

[john massey]

Is there any suggested test that I can run that will help us find the cause of this problem. For example put a STOP someplace in REDUE21 and look at OVER1, JONL! , JONL4 and JONL5

[john massey]

I took my own suggestion and inserted the following code at the end of the loop in REDUE21
If J=5:STOP

I wrote a little program that uses OUTPUT statements to look at the values which exist at the time of the stop instead of messing with it on the home screen. It looks like this:

Output(1,1,"L4 "
Output(1,5,⌊JONL4 // JONL4 holds reaction times. These values are OK for example in my test it contained 4 6 3 3 3
Output(3,1,"L5 "
Output(3,5,⌊JONL5 // JONL5 should contain reaction times > 3 seconds it should contain 1 2
Output(6,1,"L1 "
Output(6,5,⌊JONL1 // JONL1 should contain values where there are errors.
Pause

Here is the little program that relates JONL4 and JONL5. The values in JONL5 were 1 2 2 1 2 1 2. Notice that the first two numbers are the same then two reverse repeats.

For(J,1,dim(⌊JONL4
If 3<⌊JONL4(J
J→⌊JONL5(1+dim(⌊JONL5
End

J→⌊JONL1(1+dim(⌊JONL1 // this the error handler when the child inputs an incorrect answer. It contained 2 3 4 Since J can only have 1 3 5
Something is not working correctly here either.

Please help me. I feel we are very close but I have no idea what can be done.

thanks in advance
