|

| 67 | <p>You can specify a range of consecutive values in a single <code>case</code> label,
|
|---|
| 68 | like this:
|
|---|
| 69 | </p>
|
|---|
| 70 | <div class="example">
|
|---|
| 71 | <pre class="example">case <var>low</var> ... <var>high</var>:
|
|---|
| 72 | </pre></div>
|
|---|
| 73 |
|
|---|
| 74 | <p>This has the same effect as the proper number of individual <code>case</code>
|
|---|
| 75 | labels, one for each integer value from <var>low</var> to <var>high</var>, inclusive.
|
|---|
| 76 | </p>
|
|---|
| 77 | <p>This feature is especially useful for ranges of ASCII character codes:
|
|---|
| 78 | </p>
|
|---|
| 79 | <div class="example">
|
|---|
| 80 | <pre class="example">case 'A' ... 'Z':
|
|---|
| 81 | </pre></div>
|
|---|
| 82 |
|
|---|
| 83 | <p><strong>Be careful:</strong> with integers, write spaces around the <code>...</code>
|
|---|
| 84 | to prevent it from being parsed wrong. For example, write this:
|
|---|
| 85 | </p>
|
|---|
| 86 | <div class="example">
|
|---|
| 87 | <pre class="example">case 1 ... 5:
|
|---|
| 88 | </pre></div>
|
|---|
| 89 |
|
|---|
| 90 | <p>rather than this:
|
|---|
| 91 | </p>
|
|---|
| 92 | <div class="example">
|
|---|
| 93 | <pre class="example">case 1...5:
|
|---|
| 94 | </pre></div>
