Comprehensive study of nasm covering fundamental concepts and advanced applications.
As programs grow, managing code becomes harder. NASM supports procedures (functions), macros, and modular code organization.
A procedure is a block of code you can call from anywhere in your program. This keeps your code organized and reusable.
my_func:
; code here
ret
Macros let you define reusable snippets. They are replaced by actual instructions at assembly time.
%macro print_hello 0
mov eax, 4
; ... more code
%endmacro
NASM allows splitting code into multiple files and linking them, making large projects manageable.
Modular programming is key for team projects and large systems, like device drivers or game engines.
Defining a procedure to add two numbers and return the sum.
Creating a macro to print messages repeatedly.
Procedures, macros, and modular programming help you write organized, reusable, and maintainable assembly code.
