Pass a set of numbers {1,2...,n} as an argument to my program

Pemby 04 Oct 2017 04:15

This is my first time programming a TI 89, and I am not clear how variables are allocated. That is, are variables for single values? or can I pass a set in as a variable and TI-BASIC knows what to do? Or is there a special variable for the set? Or is there a better approach? Make build a data object based on N amount of inputs? Not sure what the best method is here.

For simplicity and context:
I am writing a program that will be used to enter a list of numbers, (as a set, or convert to set) then throw it at the mean(x).

In reality, I am doing something a tab more complicated but the above should get me started!

Thanks for your time!

If I understand, you're asking if you can create a list variable using regular variables instead of L1, L2, etc. The answer is yes, you can do this. Just create your list and store it to your variable (variables can be eight characters long). The 89T will automatically identify it as a list. The same goes for other variable types (which is why 68k Basic is so awesome).

I don't have my 89T on me, but I think this is the program you want:

Prgm
Input "List Size?", size
size→dim(list)
For i,1,size
Input "Number", num
num→list[i]
EndFor
EndPrgm

I can't guarantee that this is 100% accurate, but it should give you some kind of starting point for your program :)

How would I read off that list to a set? e.g {1,2,3}

What do you mean by set? Do you mean to display it like:

Disp list
