FSX-MS Converting LINDA Lua script to FSUIPC script?

[VeryBumpy 272]

I'm as useful at coding as an eye dropper at a forest fire.

I'm trying to perform a simple toggle: Toggle open/close the front door

Note:the default FSX door toggle key command map does not work in this plane and I do not want to use a mouse for this

 

Is anyone good at Lua coding FSUIPC that can help please?

The LINDA code below works with a button within LINDA but I want to map a keyboard press within FSUIPC.

function DC6_ExitFwd_open ()

    ipc.writeLvar("dc6_446_obj", 1)
    DspShow ("Frnt", "open")
end

function DC6_ExitFwd_close ()

    ipc.writeLvar("dc6_446_obj", 0)
    DspShow ("Frnt", "clse")
end

function DC6_ExitFwd_toggle ()
	if _tl("dc6_446_obj", 0) then
       DC6_ExitFwd_open ()
	else
       DC6_ExitFwd_close ()
	end
end

For info sake to others....after much, much research and suggestions from John Dowson, this is a working answer:

function DC6_ExitFwd_open ()
    ipc.writeLvar("dc6_446_obj", 1)
    ipc.display("Front door OPEN")
    ipc.sleep(4000)
end

function DC6_ExitFwd_close ()
    ipc.writeLvar("dc6_446_obj", 0)
    ipc.display("Front door CLOSED")
    ipc.sleep(4000)
end

function DC6_ExitFwd_toggle ()
    if ipc.readLvar("dc6_446_obj") == 0 then
       DC6_ExitFwd_open ()
    else
       DC6_ExitFwd_close ()
    end
end
