Definitions and constants for Placalc interface to SwissEph
This should only be used for porting older Placalc applications.
All new applications should directly use the Swiss Ephemeris API.
A programmer using the Placalc API needs only to include this file
in his code, and link his application with the SwissEph library.
There is no documentation, as it is only intended for porting old
existing Placalc applications.
The Placalc API is not supported in the Windows DLL versions of
Swiss Ephemeris.
