AppleScript to display notifications of closed apps with each separated, with a coma "," This is the AppleScript I am using..       

    tell application "System Events"
set listOfProcesses to (name of every process where background only is false)         
tell me to set selectedProcesses to choose from list listOfProcesses with multiple selections allowed  
set myResult to ""  
    end tell        

   --The variable selectedProcesses will contain the list of selected items.
repeat with processName in selectedProcesses
do shell script "Killall " &amp; quoted form of processName
    end repeat
repeat with s in every string in selectedProcesses
set myResult to myResult &amp; " ," &amp; s
    end repeat
tell application "Finder" to display notification "Apps closed successfully:
" &amp; selectedProcesses




Please tell me a way to separate to results in displayNotification by a coma.
In this case, the two apps are Notes and Reminder..
The Notification looks like this-
Just need to replace selectedProcesses with myResult 

tell application "Finder" to display notification "Apps closed successfully:
" &amp; selectedProcesses
