    Re: Zero-Altitude Shot

    Dear Paul,

    You made a notice here:

    If (altitude < 0) or (X < 90), replace Z with its supplement:
    Z = 180 - Z
    Do the adjustment only when EXACTLY ONE of the conditions is true.

    Could you please give an example when both conditions are true and the Z must not be altered. (this is how I understand your warning)

    By the way, how does your implementation work with the "folded" scales by Gary LaPook?

    Thank you in advance.

    Warm regards,
    Tony
