| <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. |
