The following code concatenates three arrays:
var num1_array:Array = [1,3,5];
var num2_array:Array = [2,4,6];
var num3_array:Array = [7,8,9];
var nums_array:Array=num1_array.concat(num2_array,num3_array)

are not broken into separate elements in array
var a_array:Array = new Array ("a","b","c");
// 2 and 3 are elements in a nested array
var n_array:Array = new Array(1, [2, 3], 4);
var x_array:Array = a_array.concat(n_array);
trace(x_array[0]); // a
trace(x_array[1]); // b
trace(x_array[2]); // c
trace(x_array[3]); // 1
trace(x_array[4]); // 2, 3
trace(x_array[5]); // 4
