TIB: Re: Infinant requesting on ti-89 basic
One way to do this is to use indirection on the 89. You input the number of
variables to be stored from the user, then you make a loop which stores
other inputs to variables.
Example code:
:Input "How many variables?",n
:For x,1,n
: Input "Value?",#("a"&string(x))
:EndFor
And now you'd have n variables named a1,a2,a3... etc.
Another way to do it, which I do more often, is to input lists. You have
the user input one variable, but in list form so there can be as many values
as needed.
Example code:
:Disp "Values?"
:Disp "(separate with commas)"
:InputStr x
:expr("{"&x&"}") /->/ x
So you'd have a list named x containing all the values.
