Program Structure Best Practices

Code Organization

Well-organized assembly code is easier to understand and maintain.

Best Practices

1. Use Comments Liberally

// Calculate circle area: PI * r^2\nMOV R0, #5       // R0 = radius\nMUL R1, R0, R0   // R1 = r^2\nMOV R2, #3       // R2 = PI (approximated)\nMUL R3, R1, R2   // R3 = area

2. Document Register Usage

// Register allocation:\n// R0 = width\n// R1 = height  \n// R2 = area\n// R3 = perimeter

3. Group Related Instructions

// Initialize variables\nMOV R0, #10\nMOV R1, #20\n\n// Perform calculation\nADD R2, R0, R1\nMUL R3, R2, #2

4. Use Consistent Formatting

Align your code for readability:

MOV R0, #5       // Load first value\nMOV R1, #10      // Load second value\nADD R2, R0, R1   // Calculate sum
