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