PREDICT Version 2.0.2d For DOS Released

Hi folks.

Today I released an updated DOS version of my satellite tracking and
orbital prediction program, PREDICT.  Version 2.0.2d includes the
following changes from the previous version:

* A solar illumination feature was added to predict the percentage
  of time a satellite spends in sunlight per day.

* Orbital predictions for satellites that appear to have decayed
  since the last Keplerian orbital update are no longer attempted
  by the program.

* Date and time used to start orbital predictions may now be
  abbreviated to Day/Month/Year only (00:00:00 is assumed).
  The default remains the current date and time.

* System clock/calendar is now read to millisecond precision,
  permitting more "lively" real-time tracking mode displays.

* The UTC timezone offset now may be set correctly for users living
  in half hour timezones.

* Internal timezone calculations are no longer confused by environmental
  variable TZ.  If TZ is properly set to a timezone name (as required
  by some other satellite tracking programs), the TZ setting is used by
  PREDICT instead of the UTC timezone offset specified in the predict.qth

* The command-line parsing code was modified to prevent segmentation
  faults from occurring if command-line options are incorrectly issued.

* Some other minor coding changes were made.

PREDICT is free software.  It may be downloaded from

Expect a new Linux version VERY soon.  :-)

An article describing the development and use of PREDICT is expected
to appear in the July (Science and Engineering) issue of "Linux
Journal" magazine.

(Yes, things have been quite hectic lately...)
