I am trying to figure out precisely what is destructive overlap. Does
destructive overlap
imply nonconcurrent copy (and vice versa)? For example:
ds 0d
a ds 12x
b ds 16x
mvc a(16),b
Here is an overlap but it is non-destructive. I would assume the copy
is concurrent?
But if I code
mvc b(16),a
the overlap is destructive (ie b won't necessarily be an exact copy of
a). Would a
concurrent copy occur? (in this case, a concurrent copy could occur
without affecting
the result).
Thanks, Greg Smith
