I've been trying to create a program that writes a table of strings to a file, but I can't figure out how to make it start a new line.
Here is the code:

function new(data,page)
f = io.open(page,"w")
for _,line in ipairs(data) do
  f:write(line,"\n")
end
f:close(page)
end

Here is the line that calls the code:

new({"Hello World!,"Lua is cool"},"test")

Here is the file:

Hello World!Lua is cool

I've never used io, I stick to fs, however I'm not sure why you are writing multiple times anyway.

local formatted = table.concat( data, "\n" )
f:write( formatted )

I think notepad uses a different new line format because when I open the file with notepad it's all on one line, but when I open it with notepad++ or wordpad the lines are separate.

Yes, notepad uses a return ( "\r" ) for it's new lines. Use "\r\n" if you want to fix that.

If you use fs.open() to get your file handles, they'll have access to a writeLine() function (in addition to write()) which automatically handles the line breaks for you.
