1. Introduction to MPLAB IDE

2. What is IDE? Integrated Development Environment (IDE)
Collection of integrated programs (tools) to write assembly programs, assemble, execute, and debug programs.
Microchip IDE is called MPLAB IDE

3. Writing Assembly Programs / and IDE Structure

4. File Structure in IDE Project_name.mcp Project_name.mcw
Project_name.mcs
code_listing.asm
New project
Code listing

5. Line Number which has an error. Read the error and correct it.
