Yes, they are both general options, so showing them in 2 differing 
places indicates that they can be, 1, before the inputs (A), or 2, after 
the inputs (F), or 3, both A & F, doesn't it? Or do they all have to be 
in one place?

Sorry if this seems anal-retentive, but I'm anal-retentive *and* an 
engineer (so, doubly anal -- wipe it 'til it bleeds). :-)
