# A Deep Dive into the Turbo Pascal Compiled Code

## Overview

This is a walkthrough through the compiled code of an **[basic Pascal program](docs/MAIN.md)** that does nothing. The source was compiled under Turbo Pascal 7.0 (**TP7**). Because **TP7** uses **Smart Linking**, the final **.EXE** file will not contain any code or variable that is not called, used, or referenced. The main content within these pages refer to this **[basic Pascal program](docs/MAIN.md)**. On the final section (**Functions/Procedures**), we attempt to disassemble and analyze **System Library** functions and procedures that are normally not included in final **.EXE** generated for the **[basic Pascal program](docs/MAIN.md)**. That section will be updated and expanded as we are able to analyze more code.
