Guide: Hello, World

Navigate to guides/hello-world/support/.

Open the hello_world.asm file, assemble it, and run it. Notice the display of the message Hello, world!

Note that:

• The hello_world.asm program uses the puts() function call (an external function of the current module) to perform the display. For this, it puts the argument on the stack and calls the function.
• The msg variable in the hello_world.asm program contains the byte 10. This symbolizes the line feed character (\n), used to add a new line on Linux.

Ending with \n is generally useful for displaying strings. The puts() function automatically adds a new line after the displayed string, but this must be explicitly added when using the printf() function.
