I am making a concept program for personal use. Given a time, it would play the music CD in the CDROM drive. I think I can get Euphoria in a loop until the time element is what I wan= t. But I play CDs by pushing the button on the CD-ROM. Is there some sort = of interrupt I could use to do that and to jump to the next track? --Alan =

Look at RDS site, on ther archive page is a file contributed by Jacques that let's you control your CDROM (play, stop, next, etc...). Look at the source code.

Thanks for the reply. I've downloaded the library you referred me to, an= d there are a few problems. Does anyone know what happened to sbcard.e, an= d when I need this library? Also, there is a function (actually a few) involving the parameter word status which Euphoria wants a type (I think = it means sequence, atom, integer, or object). At this point, I just don't know enough of Euphoria to pull up the sleeves and follow the program all= the way through, let alone my doubts as to my archive's completeness. Oh= well, no free lunch. --Alan =

I tried this program. Why doesn't it run in a loop until 20 minutes afte= r the hour? atom t sequence d d =3D date() t =3D 0 while t =3D 0 do t =3D d[5] =3D 20 end while system("c:\\cdp\\cdp.exe 2", 0) =

I think you have to keep updating your variable d. See below. > -----Original Message----- > Subject: Re: Playing CDs with Euphoria > > I tried this program.

K. I got it working. Now I have a mini-alarm clock. For my use, I won't bind it because I can just hop in and change the A SINGLE LI= NE to reflect the time and another (maybe) to change the track. Then, I can= leave the computer on and wake up with my favorite CD. (Of course, I can= 't distribute it because I launch the CD externally, but its good enough for= me right now). I should have seen the illogic in my buggy program, but I was rushing. = That's not something a relatively new programmer should do. But this brings up a good point. I wrote that code, buggy as it was, in less than= five minutes. Euphoria is fast to write in! I can't even do my homework= that fast! Lastly, as a conceptual issue (explaining how would be way over my head right now), but can I use Euphoria to write TSRs? Thanks again. --Alan =

Euphoria interpreter (ex.exe, exw.exe) can't be launched as a TSR. If you need a TSR it doesn't matter if you poke it into memory... it'll never stay resident after Euphoria terminates. Read the documentation, there it says that if there's any allocate()-ed memory when your program ends, Euphoria will free() it automatically, thus terminating the illusion. If you use exw.exe (under win32) maybe there's a chance you can make something: leave your Euphoria program running on one shell box (pseudo-TSR). I don't know how you can interact with other shell boxes... but take a try, maybe it works! Regards, Daniel Berstein daber at pair.com
