<h1>EXPORT/XREF, IMPORT/XDEF, GLOBAL</h1>
<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.</p>
<table>
<caption>Import/export commands</caption>
<thead>
<tr>
<th scope="col">Command</th>
<th scope="col">Meaning</th>
</tr>
</thead>
<tr>
<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>
</tr>
