end

local str0
    print ("Hello world, you are being ADDOS'd")
print (str1)

local str1
    print ("Hello world, you are being ADDOS'd")
print (str0)

local str2
    print ("Game is a game and is used to identify a block .3.")

local str3
    print (" With out using the game or workshop command you will probably fail with scripting.")

print (str2)
print (str3)

function YouCanRepeatMe ()
    print ("You're trapped")
    print ("Have fun >:3")
    print ("Find a way out")
end

YouCanRepeatMe (str3)

Alright so I made a script that's just for lol's and want to say what happens is that it's supposed to loop forever and make someone crash but if they dont crash they die wouldn't work and someone told me to add

a = 5 while a > 1 do end

but then it says Error in script: '<eof>' expected near 'end' and I dont understand what to do, please help
