You will need to provide us with a bit more context. As you can see
with a normal function like 'print', the code operates as expected:

1 ONE
2 TWO
3 THREE
What could be happening is that the portcardlog function is erroring,
causing whatever the overall handler is to exit. For example:
> function exitfunc(...)
>> print(...)
>> os.exit()
>> end
> slot_tbl = {"ONE", "TWO", "THREE"}
> for k,v in pairs(slot_tbl) do
>> exitfunc(k, v)
>> end
1 ONE
Please give us some more information, if you can.
