The AppleScript Studio Workshop

This article on MacTech summarizes the loop flow control structures in AppleScript which apparently amounts to the “repeat” command.

repeat
   -- code
end repeat

this will repeat indefinitely but you can exit the repeat within such a block by adding something like this:

if stopMe = true then
   exit repeat
end if

You can also repeat a fixed number of times:

repeat 5 times
   -- code
end repeat

You can also repeat until some condition:

repeat while keepGoing = true
   -- code
end repeat

repeat until stopMe = true
   -- code
end repeat

Finally there is a kind of repeat which is familiar to anyone who has used increments in for loops in other programming languages:

repeat with x from 1 to 10
   -- code which can refer to the number x which increases with each repeat
end repeat
