Sure.  0 is not equal to 1, so the test is false, and the clause isn't
executed at all.  But if you try:

	<< WHILE 1 REPEAT OFF END >>

then you'll have problems.  (You only need 1, not 1 1 ==, because any non-zero
real is considered to be a value of "true", while 0 is "false".)

If you execute that beast, check page 666 of the instructions; step 4 tells you
to press and hold ON, press and release the third key from the left in the top
row (the menu key with the C next to it), and release on.  This performs an
attention operation that is less severe than a memory reset.  On the 28, it
interrupts processing, clears the stack, and goes to the HOME directory.
