Created a simple stylesheet, linked to it, and removed body color attributes defined there. This reduces repetition and separates style and presentation.

<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>
