Do you want inverse and side shot or more complicated stuff?

            
FWIW here is an inverse routine

To inverse between two coordinates you can use this program:

LBL A
ROLL DOWN
x<>y
ROLL UP
-
ROLL DOWN
-
ROLL UP
x<>y
y,x -> r, theta
x<>y
x<0?
XEQ B
->HMS
x<>y
RTN
LBL B
360
+
rtn


For example you occupy:
N = 2,000,000.000
E = 1,000,000.000
and you want the inverse to:
N = 2,000,100.000
E = 999,900.000

On the calculator enter:
2,000,100.000
ENTER
999,900.000
ENTER
2,000,000.000
ENTER
1,000,000.000
XEQ A

You should get an azimuth of 315.0000 in the y register
and a distance of 141.4214 in the x register.
