76<p>Advance the location counter of the current section to
77<var>new-lc</var>.  <var>new-lc</var> is either an absolute expression or an
78expression with the same section as the current subsection.  That is,
79you can&rsquo;t use <code>.org</code> to cross sections: if <var>new-lc</var> has the
80wrong section, the <code>.org</code> directive is ignored.  To be compatible
81with former assemblers, if the section of <var>new-lc</var> is absolute,
82<code>as</code> issues a warning, then pretends the section of <var>new-lc</var>
83is the same as the current subsection.
84</p>
85<p><code>.org</code> may only increase the location counter, or leave it
86unchanged; you cannot use <code>.org</code> to move the location counter
87backwards.
88</p>
89<p>Because <code>as</code> tries to assemble programs in one pass, <var>new-lc</var>
90may not be undefined.  If you really detest this restriction we eagerly await
91a chance to share your improved assembler.
92</p>
93<p>Beware that the origin is relative to the start of the section, not
94to the start of the subsection.  This is compatible with other
95people&rsquo;s assemblers.
96</p>
97<p>When the location counter (of the current subsection) is advanced, the
98intervening bytes are filled with <var>fill</var> which should be an
99absolute expression.  If the comma and <var>fill</var> are omitted,
100<var>fill</var> defaults to zero.
