What shouzld be displayed in various compatible modes?

123456789
7

I got:

123456389
7

which is about what I expected, but I am not sure that the correct
answer isn't compiler dependant. Does the standard address actual
order of execution for things like this? Or side effects?

Net Express 3.1:

123456789
7

I think the subscripts should properly be calculated before the MOVE,
as Net Express apparently does here.
