Controlling the Path of Your Program

In NASM, you can create complex behaviors using jumps, loops, and conditional logic.

Types of Jumps

• Unconditional Jumps: jmp label — jumps no matter what
• Conditional Jumps: je, jne, jg, jl, etc. — jump only if a condition is true

Creating Loops

Combine labels and jumps to repeat actions:

mov ecx, 10
my_loop:
    ; do something
    loop my_loop

Making Decisions

Use instructions like cmp (compare) and test to set flags, then jump based on the result.

Why Control Flow Matters

• Makes your code dynamic and powerful
• Lets you solve real-world problems like searching or sorting

Mastering control flow means your NASM programs can do almost anything!
