In this video, we introduce Macro Processor Basics, explaining the features of macros, their facilities, and different types of macro parameters used in System Programming.

🔹 What You’ll Learn:
✅ What is a Macro Processor?
🔸 A system that expands macros before program assembly.
🔸 Difference between Macros and Subroutines.
✅ Features of Macro Facilities:

✅ Types of Macro Parameters:
🔸 Positional Parameters – Passed based on their position in the macro call.
🔸 Keyword Parameters – Passed by specifying parameter names explicitly.
🔸 Default Parameters – Providing default values when no arguments are passed.
🔸 Variable Parameters – Handling a variable number of arguments in a macro.
✅ Advantages of Macros in Programming:
🔸 Reduces Code Redundancy – Helps in code reuse.
🔸 Improves Program Modularity – Simplifies code structure.
🔸 Enhances Execution Speed – Expands macros before execution, avoiding function calls.

📌 This video is perfect for students learning System Programming, Assemblers, and Compiler Design.
