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