From the main help file:

cPPC - True if the application is running on a Device and false if it is running on the Desktop.
False
True
Version (Basic4ppc version)

So you can set the app by cheking if it is running on the device, if not its on the desktop...

.......
If cPPC= True then RunOnDevice Else RunOnDeskTop
.......

Sub RunOnDevice
'Set the app to run on the device
......
End sub

Sub RunOnDeskTop
´Set the app to run on DeskTop
......
End Sub
