Tables and things

So I want to be able to write to a table, like adding an account with a balance, but I have searched the internet and haven't found much but of things that want to explain what tables are and how they are different in lua. Also I would like to know if it's possible to edit a global var in a different program on the same computer? If so could someone leave an example?

function bankBanner()
term.clear()
term.setCursorPos(1,3)
print("==================================================")
term.setCursorPos(13, 3)
print("Buttars' bank of Nigeria")
term.setCursorPos(1,13)
print("==================================================")
end
bankBanner()

function createAccount()
end

account = {
{name = "Buttars", password = "1590", balance = 9000}

}

Yes, you can edit globally defined variables with programs - however if the other script defines it on run, it'll be set to that value.

For instance,

account = {name="hello"}

Then another program:

print( account.name )

As for tables, you probably want to know how to save/load a table. textutils.serialize turns a table into a string, which can then be written to a file.

What did you search???

Doesn't matter, here's a good explanation of tables:

It is not good idea because your variables can remove from computer on server restart or you shutdown computer.My prefer save variables into a program like "accounts". You can do this with FS API http://computercraft.info/wiki/Fs_%28API%29

You can make your serialize system but it is hard for beginners. You can serialize when save and unserialize when load your accounts with they;
