Tunes v1

[Carlo Hogeveen]

I turned the quick hack I posted yesterday into a proper tool:
- Added documentation.
- Made the code readable.
- Improved the sound quality (on my computer, your mileage may vary).
- It should no longer be necessary to play a tune overly slow.
- Doubled the amount of predefined tunes. :-)
- Added a menu:
- It lets you set the duration in milliseconds of the shortest note:
You can set it higher/lower to play a tune slower/faster.
- It lets you pick a tune from all the predefined tunes.
- It lets you play the selected tune! :-)

Tune notation is based on real music notation.

Interesting. 

FYI: 'Shortest note' still has to be 400 (instead of default 200) here to get recognizable music output.

> The tool cannot play notes below C2 and above B8.

Maybe this is something SemWare might be able to resolve?

FYIO:

C2 corresponds to a frequency of 65.41 Hertz

B8 corresponds to a frequency of 7902.13 Hertz

 Q. TSE: About Sound():

Turns on the PC speaker and causes it to sound at a specified frequency, for

the specified duration.

Syntax:     Sound(INTEGER frequency, INTEGER duration)

            - frequency is the pitch of the tone to be issued, in hertz

              (cycles per second).

            - duration is the time, in milliseconds, for the tone to persist.

Returns:    Nothing.

Notes:      Under WINNT4/2000/XP, Sound() performs as stated.

            Under WIN95/98/Me, frequency and duration are ignored, and the

            following action occurs:

            If the system is configured with a sound card, the "default sound

            event" is played; otherwise, the "standard system beep" is sent

            to the PC speaker.

Examples:

            /********************************************************

             Sound the PC speaker with a 1000-Hz signal for about 1

             second (WINNT4/2000/XP ONLY)

             ********************************************************/

            Sound(1000, 18)
