Hi, I have recently started using LINDA and can I say what a great product this is. Makes assigning switches very simple and easy. I am a cockpit builder who enjoys a little programming no and again. For one of my programs which i use to switch on/off annuicators for my overhead panel, I write values to a range of offsets 66C0 - 66D0, which is marked for general use in the FSUIPC programmers guide. It looks like LINDA is also using this range off offsets as I was wondering if anyone has a list of the used offsets by LINDA so i can amend my program to not use these offsets. Simon

Simon, Yes, LINDA occupies 66C0 offset (all 64 bytes) as a communication pipe between GUI and Lua part.No other offsets used.
