coroutine.status problem

Im fighting with multishell and something unexpected is happening. Im checking my only coroutine created with multishell "launchProcess"

local cor = tProcess.co
print (cor)
print (coroutine.status(cor))

first print shows "thread:" and HEX code of this coroutine, but second shows "dead". Its my only coroutine so its a bit weird, as "dead" should be shown only if that coroutine ended, either with or without error. Can someone explain why is this happening and how to fix this?

Here you have full multishell, but this file is heavy under construction, so many things will change within it.

'launchProcess' runs the coroutine at the end of it using the 'resumeProcess' function so that might be your problem. What function/program does that coroutine run?

EDIT: Also, where are you putting your code (the one in the OP)?

These 3 lines were in the cullProcess function. I created function that's called manually and it still shows that all the coroutines are "dead".

function multishell.printStatus(ID)
   print (coroutine.status(tProcesses[ID].co))
end

When i enter tab with coroutine that "ended" it shows error, so everything as expected. But most recent version of my multishell is created in a way that doesnt allow to end multishell tab with id 1, but when i call function printStatus it shows "dead"

Problem solved
I used this:

to override bios, but for some odd reason reverting back coroutine.status didn't work when i used os.run() to launch my multishell. when i pasted everything into one file it works :huh:/> .
And now the question - why did second rawset didnt work when i used os.run() to launch my version of multishell?
