how to use / simulate a using declaration in unityscript

I am having trouble trying to convert this C# script to a unityscript

using UnityEngine;
using System.Collections;
using System.IO;

public class saveLoad : MonoBehaviour {

 public int[] someValue;
void SaveData()
{
using(var writer = new BinaryWriter(File.OpenWrite("FileName")))
{
	for(int o = 0; o < someValue.Length; o++){
	writer.Write(someValue[o]);
			}
writer.Close();
}
}
 
void LoadData()
{
using(var reader = new BinaryReader(File.OpenRead("FileName")))
{
for(int o = 0; o < someValue.Length; o++){
someValue[o] = reader.ReadInt32();
				
			}
reader.Close();
}
}
	
void OnGUI(){
		if(GUI.Button(new Rect(100,100,100,25),"Save")){
			SaveData();	
		}
		if(GUI.Button(new Rect(100,125,100,25),"Load")){
			LoadData();	
		}
		for(int i = 0; i < someValue.Length; i++){
			GUI.Label(new Rect(225,100+(i*25),100,25),"Data Value "+i+" :" + someValue*);*
  •  }*
    
  • }*
    }
    My problem is with the using declarations, does anybody have any suggestions on how to convert this to unityscript?

Never mind I have decided to just change the whole game to C#
