Dir Help Opening Music!

[B-Man 31]

ok, im trying to load songs from a folder using the Dir functions, but i cant seem to get it to actually take the string it reads and change it to a different variable. so i can use it later on. i dont know how much sense im making here so maybe it would be easier if you looked at the code below. Thanks for any help!

Turing:

import GUI var songNum, stream, songList, select : int var file, songName : string proc chooseSong (line : int)     Music.PlayFileReturn (songName (line))     select := line end chooseSong proc getSongs     stream := Dir.Open ("Sounds/Music")     assert stream > 0     loop         file := Dir.Get (stream)                  file := songName         exit when file = ""     end loop     Dir.Close (stream)     for i : 1 .. songNum         GUI.AddLine (songList, songName (i) (1 .. * -4))     end for end getSongs getSongs songList := GUI.CreateTextBoxChoice (20, 130, 360, 105, 0, 0, chooseSong) loop     exit when GUI.ProcessEvent end loop

could you explain what's going on in this loop?

code:

loop         file := Dir.Get (stream)                  file := songName         exit when file = "" end loop

in that loop its supposed to read first folder and take the filename and have the same as the songName string so ic an play it.
this is the part that doesnt seem to work.

What is the value of songName, and where is it set?
What is the value of file when the loop exists?

songName doesnt have a value and file should be a string value of the first file in the folder (this way i can use the songname to play the music since it the exact file name)

If songName has no value, why are you assigning it to file? file was the value of the first file in the directory, then you set it to songName, which is nothing. Perhaps you wanted that the other way around?
