Hi, I was on this List last year then I unsubscribed in May in order to go sailing 4 months with my FB navigation program. It went very well, both the sailing and the program. Now, I need some help: Could anybody tell me how to translate a 4 bytes IEEE float into a 4 bytes BCD float so that I can use it in FB? The reason is that I try to read the scenery files from the X-Plane Flight Simulator. An excellent sim for the Mac, in fact. I build a Norwegian scenery and I would like to automate levelling of the coast and lakes by writing a small FB application. Please answer direct to my email address: michel@... TIA and Merry Christmas. Michel
