### 19.10 Case Ranges ¶

You can specify a range of consecutive values in a single `case` label, like this:

    case low ... high:

This has the same effect as the proper number of individual `case` labels, one for each integer value from low to high, inclusive.

This feature is especially useful for ranges of ASCII character codes:

    case 'A' ... 'Z':

Be careful: with integers, write spaces around the `...` to prevent it from being parsed wrong. For example, write this:

    case 1 ... 5:

rather than this:

    case 1...5:
