I assume you mean without using while loops etc. You should look into the behavior of over and scan when the function that is applied is monadic. This behavior is detailed in the kx wiki iteration with over

A statement including a scan or over adverb can get you stuck in an infinite loop. Something like:

{sqrt x}\[{x>0};100]

this will continually take the square root of the previous output (with an initial input of 100) until the answer no longer satisfies x>0. So the first argument is effectively a while, even though we don't use the while key word. Is this what you were looking for?
