ImXotep,
yes, it can return an array. Look at example from TS user guide, search for SortArray, open it and see how it work.

Sorry, i'm don't see this example in this guide:
Sorts the values of a one-dimensional array in either ascending or descending order based on the specified inputs.

Note All array-based function calculations begin with array element 1.

Function
SortArray(PriceArray, Size, HiLo)

Parameters
PriceArray
The name of a declared numeric array to sort.

Size
The number of data elements (size) of the array, starting with element 1, to include in the sort.

HiLo
1 = sort descending, -1 = sort ascending


Returns
SortArray always returns 1. It will sort the values of the specified array elements in order based on the HiLo input.

and all!

In TS, click on file=>open Easylanguage Doc, then open SortArray function. It will show you how TS return a function.

Basically it is treated as procedure to return array as a variable.

the best way to return an array is to go for return as reference. please find the example function (called exfun) below.

//----------------------------------//
inputs: inarray[M](numericarrayref);
//EL code//

//end EL code//
exfun=1;


//note: M is length of array, and inarray is returned as by reference. Also, exfun=1 is required or else you will get an error from TS saying that you haven't assign a value to the function. Hope this helps!
