In this video, we explore Macro Call Within Macro Definition, demonstrating nested macros, macro expansion, and stack organization in System Programming. We also explain how Macro Definition Table (MDT), Macro Name Table (MNT), and Argument List Array (ALA) work in a macro processor.

🔹 What You’ll Learn:
✅ Understanding Nested Macro Calls
🔸 What happens when one macro calls another macro?
🔸 How macros are expanded during pass execution?
✅ Macro Processor Data Structures:
🔸 MDT (Macro Definition Table) – Stores macro body instructions.
🔸 MNT (Macro Name Table) – Maps macro names to their definitions.
🔸 ALA (Argument List Array) – Handles parameter substitution dynamically.
🔸 Stack Organization – How macros use a stack for nested expansions.
✅ Step-by-Step Execution:
🔸 Writing Source Code with a macro calling another macro.
🔸 Processing MDT, MNT, and ALA tables to expand macros.
🔸 Understanding Stack Organization for Nested Macro Calls.
✅ Example Walkthrough:
🔸 Given nested macro definitions:
🔸 Generated Macro Expansion & Stack Representation:
Tracking macro expansion through stack operations.
Assigning temporary variables dynamically.
✅ Advantages of Nested Macro Calls:
🔸 Code Reusability & Modularity – Avoids redundant definitions.
🔸 Parameter Handling through ALA – Supports multiple arguments dynamically.
✅ Challenges in Handling Macro Calls:
🔸 Managing Recursive Expansions – Avoid infinite macro loops.
🔸 Stack Overflow Prevention – Handling deep nested macros.
✅ Final Conclusion:
🔸 How Stack Organization plays a critical role in macro expansion.
🔸 Encouragement to watch upcoming videos on Two-Pass Macro Processing.
