### 5.21 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: Write spaces around the `...`, for otherwise it may be parsed wrong when you use it with integer values. For example, write this:

         case 1 ... 5:

rather than this:

         case 1...5:
