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.

That was what I meant by my question. Does the standard say that all
expressions shold be evaluated before the MOVE? Or shoud expressions
be evaluated as you progress thru the statement? Or, (and not having
read the standard this is what I would have expected based on their
handling of other items) is it un-defined and therefore left up to the
mplementor?
