expression. The next line has that logical line number. Therefore any other

<span class="command">as</span> will no longer support this directive: it is recognized only
for compatibility with existing assembler programs.
<p>Even though this is a directive associated with the <code>a.out</code> or
<code>b.out</code> object-code formats, <span class="command">as</span> still recognizes it
when producing COFF output, and treats <span class="samp">.line</span> as though it
were the COFF <span class="samp">.ln</span> <em>if</em> it is found outside a
<code>.def</code>/<code>.endef</code> pair.
<p>Inside a <code>.def</code>, <span class="samp">.line</span> is, instead, one of the directives
used by compilers to generate auxiliary symbol information for
debugging.
