This is a work in progress. Just enter the curve data you have and let it calculate the rest. If one of your inputs is degree curve it will prompt for chord or arc definition. After it calculates the curve data you press OK or "Enter" to bring up the next screen with the areas.
I would love to be able to control the input form on this like you can in system RPL on a HP50. I would appreciate any feedback and ideas.

Combined the horizontal curve calculator with a vertical curve calculator and added soft keys.

I'm glad to see people writing surveying programs for the Prime.

Hi cdodds

Thanks for program and love it. this work for me easy, but I have a problem with vertical curve. The grades in and out doesn't take negative sign. Only positive. I get message "Error:Invalid input". Did I make any mistake?

I have attached screen capture
