| 37 | <div class="paragraph"><p>Here, <em>l</em> and <em>c</em> are sequences of decimal digits and <em>f</em> is the\r | |
| 38 | source file. The first character of a source file has the position\r | |
| 39 | 1.1. A line directive causes the front end to believe that the\r | |
| 40 | character following the right parenthesis is at the line and column of\r | |
| 41 | the specified file. A line directive only affects the reporting of\r | |
| 42 | error messages and does not affect program semantics (except for\r | |
| 43 | functions like <span class="monospaced">MLton.Exn.history</span> that report source file positions).\r | |
| 44 | Syntactically invalid line directives are ignored. To prevent\r | |
| 45 | incompatibilities with SML, the file name may not contain the\r | |
