| <p><a name="index-g_t_0040code_007bline_007d-directive-378"></a><a name="index-logical-line-number-379"></a>Change the logical line number. <var>line-number</var> must be an absolute |
| expression. The next line has that logical line number. Therefore any other |
| statements on the current line (after a statement separator character) are |
| reported as on logical line number <var>line-number</var> − 1. One day |
| <samp><span class="command">as</span></samp> 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, <samp><span class="command">as</span></samp> still recognizes it |
| when producing COFF output, and treats ‘<samp><span class="samp">.line</span></samp>’ as though it |
| were the COFF ‘<samp><span class="samp">.ln</span></samp>’ <em>if</em> it is found outside a |
| <code>.def</code>/<code>.endef</code> pair. |
| |
| <p>Inside a <code>.def</code>, ‘<samp><span class="samp">.line</span></samp>’ is, instead, one of the directives |
| used by compilers to generate auxiliary symbol information for |
| debugging. |
