; test source file for assembling to binary files
; build with:
; nasm -f bin -o bintest.com bintest.asm
; When run (as a DOS .COM file), this program should print
; hello, world
; on two successive lines, then exit cleanly.
; This file should test the following:
; [1] Define a text-section symbol
; [2] Define a data-section symbol
; [3] Define a BSS-section symbol
; [4] Define a NASM local label
; [5] Reference a NASM local label
; [6] Reference a text-section symbol in the text section
; [7] Reference a data-section symbol in the text section
; [8] Reference a BSS-section symbol in the text section
; [9] Reference a text-section symbol in the data section
; [10] Reference a data-section symbol in the data section
; [11] Reference a BSS-section symbol in the data section
