My advice is to always force dereferencing of the "item" in the first place. If you don't do it yourself, AppleScript will do it each time the variable is invoked in the loop, so if you use the loop variable more than once in the loop you're improving speed.

repeat with myLoopVariable in someList

    set myLoopVariable to contents of myLoopVariable -- dereference once for all and be safe

Hello Emmanuel.

It's the first thing I tried but it failed.

set {laSource, laDestination} to {"zzz", "xyz"}

tell application "Mail"

set k to count of messages of mailbox laSource

if k > 0 then

repeat with myMessage in (every message of mailbox laSource)

set my_message to contents of myMessage

if year of (get date received of my_message) = 2005 then move my_message to mailbox laDestination

end repeat

end if

end tell

Bonjour Yvan,

I noticed Emmanuel wasn't afraid to set myMessage to contents of myMessage (myLoopVariable to contents of myLoopVariable).

Courageously, I ran it, several times, and couldn't get any error.

Trying to investigates what happens ...

It is not clear to me how Emmanuel's

"set myLoopVariable to contents of myLoopVariable -- dereference once for all and be safe"

is really "once for all" because - inside the repeat, will be repeated - won't it be ?

Francis.
