How do I save directory information from os.execute("dir") into a string?

Is it possible to save the directory info obtained from os.execute("dir") into a string form?

So in the directory <DELL> I have the files info.txt and readme.txt. I want to use os.execute("dir") and have the files info.txt and readme.txt saved into string DIR. So I guess the entire string would read something like DELL; info.txt, readme.txt.

No, but using io.popen should work.

io.popen (prog [, mode])

This function is system dependent and is not available on all platforms.

Starts program prog in a separated process and returns a file handle that you can use to read data from this program (if mode is "r", the default) or to write data to this program (if mode is "w"). 

local p = io.popen( "dir", "r" )
local output = p:read "*a"
p:close( )
-- and use output
