Ok ^_^
It does seem to be a triple-nested loop, but only if the outer loop is
static. I don't think you need to rewrite your loops unless they're
triple-nested loops.
I ran your scripts again, with similar results:
test
-- 10457
-- "100 / 5 / 10001"
test2
-- 16
-- "100 / 5 / 10001"
Then I ran three other scripts, with interesting results:
test3
-- 1154
-- "10001 / 101"
test4
-- 1144
-- "10000 / 100"
test5
-- 16
-- "100 / 5 / 10000"
Here are the scripts. First, yours again:
on test
ms = the milliseconds
repeat with a = 1 to 10000
repeat with i = 0 to 99
repeat with j = 0 to 4
nothing
end repeat
end repeat
end repeat
put the milliseconds - ms
put i & " / " & j & " / " & a
end
on test2
ms = the milliseconds
i = 0
repeat with a = 1 to 10000
repeat while i < 100
j = 0
repeat while j < 5
j = j+1
end repeat
i = i+1
end repeat
end repeat
put the milliseconds - ms
put i & " / " & j & " / " & a
end
and the three I wrote:
on test3
ms = the milliseconds
repeat with i = 0 to 10000
repeat with j = 0 to 100
end repeat
end repeat
put the milliseconds - ms
put i & " / " & j
end
on test4
ms = the milliseconds
i = 0
repeat while i < 10000
j = 0
repeat while j < 100
j = j+1
end repeat
i = i+1
end repeat
put the milliseconds - ms
put i & " / " & j
end
on test5
ms = the milliseconds
i = 0
a = 0
repeat while a < 10000
repeat while i < 100
j = 0
repeat while j < 5
j = j+1
end repeat
i = i+1
end repeat
a = a + 1
end repeat
put the milliseconds - ms
put i & " / " & j & " / " & a
end
Cordially,
