8. Assembly Language (Basic) | CMP, JL, JG, JZ Explained | Character & Number Comparison Tutorial

📝 Description:

Welcome to this Assembly Language (8086) tutorial!
In this video, we will learn 4 important programs step-by-step using CMP, JL, JG, and JZ instructions.
You’ll understand how to compare characters, detect uppercase letters, check if a number is positive, negative, or zero, and display the smaller ASCII character between AL and BL.

💻 Programs Covered:
1️⃣ Read a character and display if it’s ‘y’ or ‘Y’
2️⃣ Read a character and display if it’s an uppercase letter
3️⃣ Check if Number is Negative, Zero, or Positive (CMP, JL, JZ, JG Explained)
4️⃣ Display the smaller ASCII character (AL vs BL)

This video is perfect for beginners learning Assembly Language Programming, 8086 Microprocessor, or conditional jump instructions.
