I ran into a nice IPCready.LUA example conerning vertcal speed at landing. The first statement was ipc.setowndisplay("FRM", 0, 60, 6, 1) and the LINDA editor qualified this with " 6: attempt to call field 'setowndisplay' (a nil value)". A search on the Internet reveiled that this a new function that comes with FSUIPC v. 4.95. After installing this version, the sample code functions correctly, but LINDA continues to report the error message mentioned. With this new FSUIPC release, a number of new functions are introduced that also may need attention.
