| You can specify a range of consecutive values in a single <code>case</code> label, |
| like this: |
| |
| <pre class="smallexample"> case <var>low</var> ... <var>high</var>: |
| </pre> |
| <p class="noindent">This has the same effect as the proper number of individual <code>case</code> |
| labels, one for each integer value from <var>low</var> to <var>high</var>, inclusive. |
| |
| <p>This feature is especially useful for ranges of ASCII character codes: |
| |
| <pre class="smallexample"> case 'A' ... 'Z': |
| </pre> |
| <p><strong>Be careful:</strong> Write spaces around the <code>...</code>, for otherwise |
| it may be parsed wrong when you use it with integer values. For example, |
| write this: |
| |
| <pre class="smallexample"> case 1 ... 5: |
| </pre> |
| <p class="noindent">rather than this: |
| |
| <pre class="smallexample"> case 1...5: |
| </pre> |
| </body></html> |
