Icon says hello

Here is the customary ``hello, world'' program in Icon. Using your favorite text editor, create a file named hello.icn and type these three lines in it:

    procedure main ()
      write ( "Yarrr, matey, bilge the yardarm!" );
    end

• Every Icon procedure starts with the word ``procedure'' and ends with the word ``end''.
• Every Icon program must contain a procedure with the name ``main'', and that procedure is where execution starts.
• This program has only one line, a call to the built-in ``write'' procedure, which writes its arguments to the standard output stream.
• There is only one argument to the ``write'' procedure, a string constant enclosed in double-quote (") characters.
