If within If condition?

Is it possible to have something like:

If A>B
Then
Disp ".."
Else
If A=B
Disp ".."
Else
Disp "

Yes, you can do nested loops like this, but I believe that you have to have a then command for and else command. The loop will be run as long as the first If-then statement is true. So if the first If-then statement isn't true, it won't run anything inside the If-then loop.

Check out the If page

So…

If A>B
Then
Disp ".."
Else
If A=B
Then
Disp ".."
Else
Disp "
End
End

Thanks for your answer!

For some reason my code isn't really willing to work, this is what I got:

Menu("Welke soort rij?","Rekenkundig rij",H1,"Meetkundig rij",H2
Lbl H2
Input "t1=",A
Input "t2=",B
If B/A=1
Then
Disp "De rij convergeert"
Disp "Druk op ENTER"
Pause 
Goto 1
Else
If B/A=<-1
Then
Disp "De rij divergeert"
Disp "Druk op ENTER"
Pause 
Goto 1
Else
If B/A>1
Then
Disp "De rij divergeert"
Disp "Druk op ENTER"
Pause 
Goto 1
Else
Disp "De rij convergeert"
Disp "Druk op ENTER"
Pause 
Goto 1

For curiosity, I am trying to make a labeled program that sees whether your row is convergent or divergent by checking the first two values.
If B/A (q) >1 then it's divergent
If q=1 => convergent
If q <= -1 => divergent
If -1<q<1 => convergent

I am not very sure why mine isn't working out, I hope you can help me out with it.

Edit: the menu is showing up and it's working out well, it's whenever I input my values that it sometimes give me a syntax error (when first condition isn't met?)

I believe that is because you don't have a Lbl 1 at the beginning of your program. It is trying to find a place where Lbl 1 is becasue of the Goto 1's. The Goto command looks for a Lbl command with the same value after it

So…

Goto 2
Repeat X=50
X+1->X
End
Lbl 2

The Goto command will search through the code until it finds its Lbl counterpart, at which point it will start at that point.

Hope this helps!

Ah no I do have a lbl 1 but my code is over 200 lines long and I didn't copy all of it, I just copied the "broken" part.

I figured it out though, the issue lined on the =< -1, I wasn't supposed to use "-" but the calculator version of "-".

Thanks for all the help though, it's appreciated!

Yeah that can work. Just don't forget to add the End statements at the end or it won't work as intended.
You can have as many If statements as you want, given you don't get lost in your own code and have enough memory.
