COGO program for HP15C

[Alex Liggett]

My survey cogo programs are attached (they have now been tested using a genuine 15C). For our work there is still no substitute for having a fieldbook and a calc of some description in the field - you can't quickly or easily draw diagrams in a data logger, and there are some computations that are easier on a calculator, be it an 11C, a 48 or whatever.
