1.How would I add music to a euphoria program. Is there an include to do this?
2.How can I save information without using files but still being portable and standalone meaning the end-user does not have to install anything but my program? I want to do this because files can easily be modified. So they aren't secure.
3.If i can't use music what can I do to use and manipulate "beep" frequencies?

You need to use a library to add music to a euphoria program. BASS is good. I don't know question #2.

Windows or Linux or Both?
Windows has the MCI (Media Control Interface) API that provides routines for this, including MIDI file playing.
2.How can I save information without using files but still being portable and standalone meaning the end-user does not have to install anything but my program?
You can't. Information must be saved to files. But what sort of information are you talking about?
3.If i can't use music what can I do to use and manipulate "beep" frequencies?
Windows or Linux or both?
Windows has the Beep(freq, durn) routine, but I've never been able to get it to work for me.

If security is the issue, then you can encrypt or otherwise protect the data in them. This is not hard to do and is fairly standard practice.
Are you worried about the file data being seen or just about them being modified?

My suggestion would be to develop the game and leave such things to the later part of the development stages. All the nitty gritty stuff can really drag things down to the point of never getting the project done.

If you only plan on developing for Windows, then I suggest using the BASS Audio Library for sound/music and saving user-specific data in the registry.

I agree with Jeremy on that. The protection of the data files can wait until you have the game working. For the moment, just assume it can be done and without a lot of bother on your part.
As it gets closer to the time, you can share with us the research you have done on protecting such files and we should be able to help out then.

Just on a personal note, I believe that the Registry concept for non-Microsoft applications is evil and no one in their right mind would ever consider using it.

Using a Euphoria database is also a pretty good way of locking people out of your data.

good timing
this weekend, i've just finished wrapping
libsndfile (audio file generation/read/write)
http://www.mega-nerd.com/libsndfile/
for use with euphoria (v4) working for both Linux and Win32
halfway through wrapping pulseaudio
(audio file playback), should hopefully
have basic playback done over next few days.
any good for you?
if so, i'll post them up to the archives
at www.rapideuphoria.com

pulseaudio is basically a sound server daemon that
bundles with audio file players (pacat-simple, paplay)
that use libsndfile for playing back data streams, so
it should support everything that libsndfile provides

1.How would I add music to a euphoria program. Is there an include to do this?
On very useful cross-platform music and sound effects library is the free SDL library. For an explanation of its use and examples see my games tutorials on www.rapideuphoria.com. They can be downloaded at:
http://www.rapideuphoria.com/tutorials.zip or found in the Rapid Euphoria Archive under the 'Games' section.
Tutorial 4 onwards shows the use of both sound effects and music playing. I find the SDL library a lot easier to use than other methods, for reasons that I explain in the tutorials.
