Astrology Source Code with Asteroids

Here is public domain source code that any would-be programmer/astrologer can use as the core for any sort of astrology program a person wants to make. This source code uses the Astrodienst Swiss Ephemeris (click here) to do all planetary, asteroid, and house calculations. Please see Astrodienst's web page for the details of the Swiss Ephemeris license (click here) and other documentation.

AstrAstr contains natal, secondary progression, and transit calculations, natal chart interpretations, daily transit interpretations, single and dual chartwheels, two types of keyword features, 7 different house systems, my AstroLine graphic planetary display, a meanings form that allows you to select and read various natal interpretations for any planet in a house, sign, or aspect, plus any rising sign, a natal chart report writer, a daily transit report writer, plenty of option settings, help files, a Tip of the Day feature, two astrology fonts that can be used in any word processor application, and 90-degree wheels for displaying asteroid positions. Since this is free source code, there is currently no automatic atlas feature in the program, except the ability to interface with the ACS DOS or Windows atlases. There are geographic lists of about 2300 cities, though.
