OK, this is the correct reason. Now, take it a step further. If, instead of getting a list of valid UIDs via UID SEARCH ALL, you get the UID/sequence map via FETCH 1:* UID, do you see that you no longer need the UIDs except to in store your local cache? There are a lot of things that you can do using both UIDs and sequence numbers if you are imaginative. Note, in particular, the very useful property that UIDs are strictly ascending. -- Mark -- http://staff.washington.edu/mrc Science does not emerge from voting, party politics, or public debate.
