Is it possible to read the data in individual Variables instead of in a table?

[Dragon53535]

Yeah. But to be honest, it would take a lot longer of code than reasonable. If you want to set a variable to a specific line, just read the data into the table, and save your variable as the line you want.

local file = fs.open('file','r')
local tbl = {}
local line = file.readLine()
repeat
  tbl:insert(line)
  line = file.readLine()
until not line
local linethree = tbl[3]

Why not save the serialized table?

local data = {}
function read()
	local file = fs.open("file", "r")
	data = textutils.unserialize(file.readAll())
	file.close() -- don''t forget to close your files
end
data.writingTest1 = "Hello"
data.writingTest2 = "World"
data.writingTest3 = 123
function write()
	local file = fs.open("file", "w")
	file.write(textutils.serialize(data))
	file.close()
end

Note: untested code written on the fly

You could instead of the loop use;

tFile = file.readAll()

and acsess the first line like:

print(tFile[1])

Hope I helped... Well, I think I did.

*reads post from 2 years ago that's incorrect*
Well, crap.

Actually, it wouldn't be

filedata[1]

, it would be

filedata[0]

because computers count from 0, not 1. At least I think. ComputerCraft might be different,

Sorry, don't know how to use inline code lol

Allow me to introduce you to the wonderful world of Lua (and R, and maybe other languages).

3 year necro.. And no, Lua starts at 1 for table indexes. It is generally a safe assumption that the index starts at 0 (for most languages), but for Lua, this isn't the case.

Edit: got ninja'd, darn you, Squid.
