You must download it for it to see anything.

You don't have to yell!

function _draw()
 cls()
 if stat(102)==0 then
  dr_boxes()
  dr_files()
  dr_menu()
  rect(2,0,81,127)
  rect(81,0,89,127)
  rect(89,0,127,32)
  controls()
 else
  print("this does not work on the bss.")
  print("you must download it to see anything.")
 end
end

HWD, I think you can do:

"LS *.*"

and it will work to show all files in the directory.

I tried, but I can't get LS to work with that in code. Do you give that '.' as an argument for LS?
This is my code:

list=ls(*.*)
for i=1, #list do
 print(list[i])
end

I tried it in quotations as well, but that didn't print out anything.

In lua code, rather than the command line, you'd have to pass a string, so you'd need to put quotes around the wildcard pattern.

I don't think the code version of ls() takes an argument, though. In fact, when I just tested it, if you give it an argument, it returns nil instead of a list.

Also, even if it took an argument, you probably wouldn't use "*.*". That particular pattern is kind of a relic of DOS days, when every file intrinsically had a 3-letter extension. You had to type it that way. These days, "*" is what you want if you want to see every file, especially outside of Windows, where "*.*" will limit you to seeing files that literally have a dot in them. Windows tends to quietly treat "*.*" as "*" to make life easier for people with old habits.

Hope you don't mind the thread hijack, but on a related note I think it'd be nice if the runtime version of ls returned directories as well (either via a parameter or just leave the parsing up to us), especially as cd can be used at runtime.
