I never use them because I don't know how they work :-)

So I will take this oportunity to ask. What I can't seem to find out is:
will these commands cross bank boundaries? If not, they are not too useful,
since there's usually a chance that the memory will (unless you tell NewHandle
not to cross)

I suppose this should go on comp.sys.apple2.programmer. But the group doesn't
seem to exist here.
