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.
Hello
Of course, I tried the "dereference on itself" tip before using "dereference to an other variable". I did the second one because the first one 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 myMessage to contents of myMessage if year of (get date received of myMessage) = 2005 then move myMessage to mailbox laDestination end repeat end if end tell
the report claims:
tell application "Mail" count every message of mailbox "zzz" 4 count every message of mailbox "zzz" 4 get item 1 of every message of mailbox "zzz" message id 84246 of mailbox "zzz" get date received of message id 84246 of mailbox "zzz" date "mardi 22 novembre 2005 21:31:04" move message id 84246 of mailbox "zzz" to mailbox "xyz" get item 2 of every message of mailbox "zzz" message id 84245 of mailbox "zzz" get date received of message id 84245 of mailbox "zzz" date "vendredi 18 novembre 2005 08:36:04" move message id 84245 of mailbox "zzz" to mailbox "xyz" get item 3 of every message of mailbox "zzz" message id 84155 of mailbox "zzz" get date received of message id 84155 of mailbox "zzz" date "vendredi 18 juin 2004 14:35:13" get item 4 of every message of mailbox "zzz" "Erreur dans Mail : NSReceiverEvaluationScriptError: 4"
