User login recording (Lua Question) [SOLVED]

This following programs reads from a inserted disk to see if that person has a high enough clearance.

I wanted to know if i could have the program read from only a SPECIFIC line on the disk or a specific file on the disk so i can include additional data such as name or specific permissions. Then have the program write to its own rom, adding lines to a previous existing log.

Are there any commands that could help me do that?

Spoiler

while true do
event, param1, param2 = os.pullEvent()
if event == "disk" and param1 == "dside" or if disk.isPresent(dside) == true then
if fs.exists("disk/level") then
file = io.open("disk/level", "r")
passt = file:read()
if passt >= pass then
print("ACCESS GRANTED")
disk.eject(dside)
power(pside, colors.blue)
sleep(10)
power(pside, 0)
else
print ("ACCESS LEVEL NOT HIGH ENOUGH")
sleep(10)
disk.eject(dside)
os.reboot()
end
end
disk.eject(dside)
end
end

I solved this problem by have the program write many files to the floppy, each holding the string of info I need

print ("Corsair Security Card Programming Suite")

HorzLoadBar(5, 45, "/")

print ("Insert blank card")
while true do
os.pullEvent()
if disk.isPresent(dside) then
print ("Card detected")
write ("Enter clearance level of card: >")
local clearance = read()
write ("Enter purpose of card: >")
local purpose = read()
write ("Enter ID# of card: >")
local id = read()
write ("Enter name of user: >")
local name = read()
disk.setLabel(dside, "Level "..clearance.." Access card")
file = io.open("disk/data/clearance", "w")
file:write(clearance)
file:close()
file = io.open("disk/data/purpose", "w")
file:write(purpose)
file:close()
file = io.open("disk/data/name", "w")
file:write(name)
file:close()
print ("Card has successfuly been programmed.")
sleep(2)
print ("Please remove the card")
sleep(2)
print ("Rebooting...")
sleep(1)
os.reboot()
end
end
