The code comes from the RGBDS source and documentation zip files found on this website: http://www.otakunozoku.com/1999/08/01/rednex-gameboy-development-system/ The same website reports: "Best of all, it’s free! That’s right! Free! The executables are free to use, either for personal hobby use, or full blown commercial productions — I know of at least a dozen commercial games you can purchase that are written with RGBDS — and the source code is free to modify. "The only thing I ask is that you do not charge for either distributing the executables or source code, and any derivative works you give credit to the original authors of the tools. That means you have to say “Thanks” to the original authors SurfSmurf and Otaku." Signed-off-by: Vegard Nossum <vegard.nossum@gmail.com>

<P>Importing and exporting of symbols is a feature that is very useful when your project spans many source-files and for example you
|
|
need to jump to a routine defined in another file.<BR>

<TD>IMPORT (or XREF) <I>label</I>[,<I>label</I>,...]</TD>

<TD>This instructs the assembler to define label as if it were present
|

in the current file but leave the address calculation to the linker.</TD>

<TD>EXPORT (or XDEF) <I>label</I>[,<I>label</I>,...]</TD>
|
|
<TD>The assembler will make <I>label</I> accessible to

other files during the link process.</TD>

<TD>If <I>label</I> is defined during the assembly it will be exported,

if not it will be imported. Handy (very!) for include-files.</TD>
