Command window output not displaying everything?

The command window does not display all of the output in my code. This is a very recent problem, not sure what I could have done to start it. As an example, sometimes I want to see how the variable "a" changes in a loop, so I will include a line of code that says

disp(a);

Usually, I'd be able to see all of the outputs. For example, if I was counting to 100, I'd be able to see the output 1,2,3, etc. Recently, however, MATLAB "deletes" all of the outputs except the very last output, so I only see

a =
    100
   
    

Any other output is unable to be accessed by hitting the up arrow. It seems that MATLAB will momentarily display it, but then it disappears. Anybody know what to do? Not sure where this problem came from, or how to fix it. I've checked out the preferences for command window, but "Automatically delete output?" does not seem to be an option. Cheers.

What else is in your code? Do you have the ghastly

clc

sitting somewhere in code called within your loop?

Yes, that was it! It seemed that at one point I thought I was typing in the command window and was instead typing in the editor... how embarrassing. Thank you!!
