Place that in your main function, or the first one your channel runs.

How do you detect that you need to display it ?
Roku level 3 or less than 4 ?

[RokuJoel]

Best bet would be to use it on all platforms, no need to detect. If you must detect version, use rodeviceinfo:

function IsNotLegacyDevice() as boolean
    version = CreateObject("roDeviceInfo").GetVersion()
    major = Mid(version, 3, 1)
    minor = Mid(version, 5, 2)
    build = Mid(version, 8, 5)
 
    if major.toint() >= 4 then
        return true
    else
       return false
    end if
end function

I must have missed something ????

I created a subroutine called from the main with a combination of the above snippets, displayed the splash screen with a 1 sec wait. Looked good.
Then returned and the program closed ???? ( screen fell off the stack )
Now the funny thing is, it didn't close right away. Got through several subroutines before it died. And appears to die in different spots.

Changed the subroutine to return the screen object and had the main caller keep an instance. Now it works !!!
Changed the subroutine to close() the screen object and it fails !

Where is it written that if you display a screen, close it and it was the only one, that it implies "PROGRAM END" ????
Maybe the program had something else to do ! In this case, the entire program.

Now to have this work, I have to keep the splash screen object laying around.

It has always been true that a channel exits when you close all of its screens and there has been a fair bit of discussion about it here over the years.
