< Project 3 - SIC/XE Linking Loader >

0. How to execute program

* After unzipping, there should be:
- 9 *.h header files
- 9 *.c source code files
- Makefile
- Document.docx
- README.txt
- opcode.txt
- proga.obj, progb.obj, progc.obj
- copy.obj

* Then, type the following to execute program:
$ make
$ ./20161577.out

* To cleanup directory after execution, type:
$ make clean


1. Description

This is the third project for the System Programmig course in the Department of Computer Science and Engineering at Sogang University, Seoul, South Korea.
The implementation of the SIC/XE Machine Linking Loader is added to the previous project.
