I'm currently working on a program called UPaint which uses a table as a canvas, and I would like to know how I would be able to save that table as a text file and reload it. Thanks in advance! :D/>

local myTable = {}                           -- Fill this with whatever.
local myFile = fs.open("someFileName", "w")  -- http://www.computercraft.info/wiki/Fs.open
myFile.write(textutils.serialize(myTable))   -- http://www.computercraft.info/wiki/Textutils.serialize
myFile.close()

local myFile = fs.open("someFileName", "r")
local myTable = textutils.unserialize(myFile.readAll())
myFile.close()

Thank you! I looked through textutils, but I didn't quite get what the default text meant. If I did, I would've gone to the actual textutils.serialize page and looked closer. XD
