The statements between a 'while' and a 'repeat' should ultimately push a value to the stack that will determine if the loop executes the body of the 'repeat' block. === Examples === 5 ->y while <-y gt(0) #is y greater than zero? repeat #repeat this section of code trace(<-y) <-y sub(1) ->y #subtract 1 from y so we don't end in infinite loop endwhile
