<var>new-lc</var>.  <var>new-lc</var> is either an absolute expression or an
expression with the same section as the current subsection.  That is,
you can't use <code>.org</code> to cross sections: if <var>new-lc</var> has the
wrong section, the <code>.org</code> directive is ignored.  To be compatible
with former assemblers, if the section of <var>new-lc</var> is absolute,
<samp><span class="command">as</span></samp> issues a warning, then pretends the section of <var>new-lc</var>
is the same as the current subsection.

   <p><code>.org</code> may only increase the location counter, or leave it
unchanged; you cannot use <code>.org</code> to move the location counter
backwards.

<!-- reference to "undefined" (as SEG_UNKNOWN is called in this manual) -->
<!-- section. doc@cygnus.com 18feb91 -->
   <p>Because <samp><span class="command">as</span></samp> tries to assemble programs in one pass, <var>new-lc</var>
may not be undefined.  If you really detest this restriction we eagerly await
a chance to share your improved assembler.

   <p>Beware that the origin is relative to the start of the section, not
to the start of the subsection.  This is compatible with other
people's assemblers.

   <p>When the location counter (of the current subsection) is advanced, the
intervening bytes are filled with <var>fill</var> which should be an
absolute expression.  If the comma and <var>fill</var> are omitted,
<var>fill</var> defaults to zero.
