I know the interrupt mode 1 manipulates flags a lot.  In my program, I want
to use the IY register as an index register to search through an array (I'm
already using the IX register for the same purpose).  So when I change the
value of IY, do I have to disable the interrupts?  And what value do I need
to set IY to when I finish using it?
