+# This assembler file is used to include the file tiles.tim as an array named
+# 'tim_tileset' for use in this example program. Note how the variable name
+# itself is leading with an underscore (_) in this file. This is because
+# GNU C requires leading underscores for global variables, perhaps to prevent
+# function names and variable names from mixing up during the linking stage.

+# Tell assembler that the contents that follow must be in the .data section

+# This directive define the 'tim_tileset' label as a global symbol so that
+# main.c and other program modules can see this symbol during linking
+.global tim_tileset
+
+# This directive is not really required, but its best to define symbols
+# not pointing to program code as an object to help identify it as a
+# variable in debuggers
+.type tim_tileset, @object

+# The following line defines the variable 'tim_tileset' itself filled with the
+# contents of the file 'tiles.tim' by using the .incbin directive

+# declared in the C code
