Tony,
Very true. I have decided to us variables D (declination), A (assumed latitude), and M ( meridian angle LHA).
The short hand formula: Pol(TD CA - SA CM , - SM) aC Ans CD = Hc
T (tangent), C (cosine), S (sine), a (arc), Ans (answer), and Hc (calculated altitude).
To remember the pol formula I will use a football theme: Touch Down CA lifornia - SA CMontana , - Score Montana

If you put all the values in the registers (A, B, C, etc) not only your cheat-list will look nicer - it will be easier to repeat calculations.
Warm regards,
