+; test source file for assembling to Microsoft 16-bit .OBJ
+; build with (16-bit Microsoft C):
+;    nasm -f obj objtest.asm
+;    cl /AL objtest.obj objlink.c
+; other compilers should work too, provided they handle large
+; model in the same way as MS C
+
+; This file should test the following:
+; [1] Define and export a global symbol
+; [2] Define a non-global symbol
+; [3] Define a common symbol
+; [4] Define a NASM local label
+; [5] Reference a NASM local label
+; [6] Import an external symbol
+; [7] Make a PC-relative relocated reference
+; [8] Reference a symbol in the same section as itself
+; [9] Reference a symbol in a different segment from itself
+; [10] Define a segment group
+; [11] Take the offset of a symbol in a grouped segment w.r.t. its segment
+; [12] Reserve uninitialised data space in a segment
+; [13] Directly take the segment address of a segment
+; [14] Directly take the segment address of a group
+; [15] Use SEG on a non-external
+; [16] Use SEG on an external
