I tried replacing my io.read() with your io.lines() construct, but  
because the
if statements are still not working for me mine is still not  
detecting the "&"

Here is my program as it currently stands:

#! /usr/local/bin/lua

-- Read fortunes in
do
    local aline

    jar = {}
    pointer = 0
    cookie = 1
    for aline in io.lines() do
        jar[cookie .. "+" ..  pointer] = aline
        pointer = pointer + 1
        print(">" .. string.sub(aline,1,2) .. "< " .. cookie .. "  
" .. pointer)

        if ( string.sub(aline,1,2) == "&&")  then
            break
        end

        if ( string.sub(aline,1,1) == "&") then
            pointer = 0
            cookie = cookie + 1
        end
    end

    print(pointer .. " " .. cookie)
end

This incorporates your change, but cookie still increments for me,  
and pointer is
never re-zeroed, In your example none of your if statements had a  
finishing end,
am I doing that wrong??

do I need to do

if (condition) then do
    statement
    statement
end

I am trying that with the code but it is confusing me....
