If you can drive it from external program than all is fine. 2) As I see you are sending data from python in the form like this: speed-active=0 speed-active=1 speed-active=1 FG does not accepts variable names and expects input in the form 0 1 1 With respect, Alex -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

Hi!
Not sure but can this help.
Try to change ufo.nas .
remove : geo.Coord.new().set_xyz(0, 0, 0)
write:geo.Coord.new().set_latlon(0,0, 0)

Hi May I have miss something but I have in FG properties "sim/time/gmt" in the form "2009-05-16T12:08:16", "sim/time/gmt-string" as "12:08:16", and sub-trees sim/time/utc/... and sim/time/real/... containing year, day etc as integers.

Problem is in /src/ATCDCL/ATC.hxx , line 300

Yes. Now it is normal here. I have posted two bugs at 04/04 ("divide by
