Tables Or Storing Multiple Variables

local myTable = {}

local myTable = {test="lol",num=3}

print(myTable["test"])
print(tonumber(myTable["num"]))

myTable[<index name="">] = "value to be stored"

print(myTable["index of value to be retrieved "])

local passwords = {}

function main()
term.clear()
term.setCursorPos(1,1)

print("Enter new user:")
userNew = read()

print("Enter password: ")
passNew = read("x")

passwords[userNew] = passNew

print("Do you want to view users? y/n")
ans = read()

if ans == "y" then
  term.clear()
  term.setCursorPos(1,1)

  print("Enter user: ")
  userFind = read()

  print("Password for user '"userFind"' is '"..passwords[userFind]"'")
  read()
end
end

while true do
main()
end

1. tonumber turns strings into numbers. "1" becomes 1, "3.1415926535897932" becomes 3.14159265 (yeah, only 8 decimals). It returns nothing if the string cannot be converted into a number. But, for the record, using tonumber in that example was pointless, since myTable["num"] is a number anyways.
2. The "num" key of myTable contains a number, as you can see that in the first line.
3. The forum software messed that up. Would be something like myTable["key"] = "value to be stored".
4. Not a problem.
5. Prints the "index of value to be retrieved" key of myTable.

This declares a table but you can replace "myTable" with any name you want

To be able to store values in a table you need to use an index:
