<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>
</TR>
<TR>
<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>
</TR>
<TR>
<TD>GLOBAL <I>label</I>[,<I>label</I>,...]</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>
