CGTalk - reverse array...

I'm a little bit confused...
Isn't it possible to reverse an array via a simple syntax???
The same problem with copying an array... did not find anything about that in the manual!

for the copy problem I wrote a function, but I could not handle the reverse problem...

fn copy_array array1 array2 = (
for idx = 1 to array2.count do
(
append array1 array2[idx]
)
)

try these:

array1 = #("A", "B", "C")
array2 = #()
array3 = #()

--copying the array
array2 = for idx in array1 collect idx
--reversing the array
for idx = array1.count to 1 by -1 do (append array3 array1[idx])

try this:

myArray = #(2,1,3,4,5)

copyArray = #()

join copyArray myArray

Hi,

if using Max9, you can use DeepCopy
else try this:

-- returns a copy of an array
fn copyArray arr=
(
for i in arr collect i
)

-- returns a reversed copy of an array
fn ReverseArray arr =
(
for i=arr.count to 1 by -1 collect arr[i]
)

for i = arr.count to 1 by -1 collect arr[i]
