Objectives: Implement the Sack operating system and test it by executing application programs that use OS services.

The contract: Write the OS implementation and test it by running all the test programs and testing scenarios described below. See section 5 (Build It) of chapter 12 for details.

Classes and tests:

Class	Test Program	Test Script	Compare file
Array.jack	Main.jack	ArrayTest.tst	ArrayTest.cmp
Keyboard.jack	Main.jack
Math.jack	Main.jack	MathTest.tst	MathTest.cmp
Memory.jack	Main.jack	MemoryTest.tst	MemoryTest.cmp
Output.jack	Main.jack
Screen.jack	Main.jack
String.jack	Main.jack
Sys.jack	Main.jack

In addition You are given the Pong game to test OS together (you can use your own game for that as well). The game is in the Pong directory in the project's zip file.

Requirements: You should submit a set of classes written in the Jack language that implements the Sack OS specification.
