I think that since Image already has the list and fields in the buffer, it
would be simpler to just use *. I don't think there would be any marked
performance difference.

Ahh, yes, my example neglected to point out that the key is to remain the
same...thanks, though, Denys.

Yes.
Seriously, from a timing POV, I don't think it makes much difference.
However, you should consider the possible ramifications of a DBUPDATE for
all the items if this is a detail dataset. Keep CIUPDATE in mind.

Hi all,
Given the scenario of 10 items in a data set (each item 6 bytes
long), an Image list of all 6 of the set's items was produced to read the
data set, but only one of the items is actually updated in a given
transaction: Is it faster to produce a new list for Image to use for the
update that would only update the one item in the data set that actually
changed, or is it quicker to just update all of the items in the set using
the "*;" construct?
TIA,
Ray Shahan
