+; 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
