Hi Hal, Thanks for your reply. I wasn't aware of all these Palm applications! And I guess I need to find a better name than Pilot Navigator now... Dang! I'm in the US, have an emulator, and develop in C with PRC-tools. I won't comment on doing forms by hand in Emacs. Besides this, it's fun to write. I am getting familiar with the UI guidelines, and am keeping launch codes and multisegment for later. I don't have Bowditch yet, but I do have the French admiralty manuals and I don't see why the formulas would not yield the same results? YA
