I am a newbie with LINDA but have managed to assign a button on my Saitek X52 joystick to an existing  FSX command Panel 1 . No problems, the Panel 1 window opens up.
Now i have been playing around with my brother's Carenado King AIR B200, and the console has found a number of Lvars that are not listed  Fsx controls that i can use...... With most of them i have been assigning them in FSUIPC with the toggle parameter  and then assigning a key press. They are all working fine  However, a few switches are three-way in the vcirtual cockpit. For example there is a 3 position windshield anti-ice in the virtual cockpit which is defined in the console (roughly) as ASD_WNDSHLD_ANTIICE_PILOT.. Using the LINDA console, the switch has three positions: OFF,  ON and TEST the values are +1, 0, -1 . I have programmed  3 different keys on my keyboard in fsuipc with the different parameters  and can switch to each position correctly even thoough it is hugely wasteful using three keys ( i just. wanted to check it works ). What i need is a LUA/LINDA.FSIPC??? command that will cycle between the three positions on the one switch!!! Do i need a LUA script ? or a LINDA function or can i do it easily in FSUIPC .. im stumped !!!! any help would be greatly appreciated

No replies so  i went to the newest version of Chat GPT 4o.. i have a subscription, and posed the question. i was surprised that it answered such a specific question with ease. .. a bit scary actually the power of AI . lua fsuipc and LINDA are niche software but CHAT GPT just ripped it. I  have finally tested it  on my PC flight  simulator and B200  and it works perfectly. .I

Firstly you need linda to find teh correct LVARS as the B200 hasa lot of custom switches you wont find in FSX controls. It will also fine the value of the parameters of the LVAR which is greta  
 

Here is what Chat GPT replied to my query word for word 

To create a LUA script for FSUIPC that cycles through the positions of the three-way switch (OFF, ON, and TEST) using one key, you can use the following script as a starting point. This script will increment the switch position each time the key is pressed and wrap around when it reaches the end.

Here is the script:

Create a new LUA script file and name it something like cycle_switch.lua.

Add the code below to the file:

Save the script in the Modules folder of your FSX installation.

Open FSUIPC and assign a key press to run this LUA script. To do this:

Go to the "Key Presses" tab in FSUIPC.

Press "Set" to define the key you want to use for cycling the switch.

In the action list, select "Lua <your_script_name>". In this case, it will be "Lua cycle_switch". ( yes it was there after paling lua in modules folder!!! ) 

With this script, pressing the defined key will cycle the windshield anti-ice switch through its positions: OFF (0), ON (1), and TEST (-1). This way, you only need to use one key to control the switch.

 

-- Define the LVar for the windshield anti-ice switch

local lvar_name = "ASD_SWITCH_WDSHLD_ANTIICE_PILOT"

 

-- Define the switch positions

local switch_positions = {-1, 0, 1}

 

-- Function to cycle through switch positions

function cycleSwitch()

    -- Get the current value of the LVar

    local current_position = ipc.readLvar(lvar_name)

   

    -- Find the index of the current position

    local current_index = nil

    for i, v in ipairs(switch_positions) do

        if v == current_position then

            current_index = i

            break

        end

    end

   

    -- Determine the next position

    local next_index = current_index + 1

    if next_index > #switch_positions then

        next_index = 1

    end

    local next_position = switch_positions[next_index]

   

    -- Set the LVar to the next position

    ipc.writeLvar(lvar_name, next_position)

end

 

-- Call the function to cycle the switch position
cycleSwitch()

in my case, i  used the W  for the Winshleld Anti Ice pilot - cycle switch.lua  .. pressing  the W key repeatedly cycles the switch up and down
