Repeat statement always iterates exactly once

I'm just starting TI-86 BASIC programming with the following guessing game:

:randInt(1,10)→X
:0→A
:Repeat A=X
:Disp "Guess the number"
:Input "between 1 and 10.", A
:End

My understanding of the Repeat statement is that the block will execute until the condition is true. In my case, I find that the block executes exactly once. That means the value of A that the user enters is always the same as the random value of X, which I find hard to believe.

Any idea what I'm doing wrong?

Solution

  • Variables in the TI-86's version of TI-BASIC can be compared using the == operator. So the program becomes

    :randInt(1,10)→X
:0→A
:Repeat A==X
:Disp "Guess the number"
:Input "between 1 and 10.", A
:End
