Finding the size of an Icon string

The unary ``*'' operator, applied to a string, returns the number of characters in the string. For example, the expression

    * "foo"

Here's another example. This program prints the length of every line of its input:

    procedure main()
      while  line := read ( )  do
        write ( * line );
    end
