Any Surveyors?

I tried your program on my Droid48. I needed to use the complimentary angle of the bearing to get the correct delta latitude and delta departure in the NE quadrant, for example. Also, the precision of the resulting vector is poor. I don't know why. You could add a TMENU with a CONT label and function before your prompts. Then, you don't have to keep typing CONT after your prompts.
