This document provides instructions for using an emulator to create, run, and debug assembly language programs. It outlines the key steps as: 1) Assembling the source code into an object file using an editor and assembler. 2) Linking the object file to create an executable file. 3) Opening the emulator software, loading example programs, or creating a new program file to write and save source code. 4) Running the program by clicking the emulate button, and single stepping through instructions to observe register changes.
