WXTide32 install and operation - Version 4.6 2006/06/30
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    WXTide32 Copyright (C) 1998-2007  Michael Hopper.
    Based on XTide 1.6.2 Copyright (C) 1997  David Flater.
    ..and WinTide from 1996 by Paul Roberts.
    Also starring:  Jef Poskanzer; Jack Greenbaum; Rob Miracle;

    This version of the windows port hacked by Mike Hopper who is solely
    responsible for the program and especially any station index inaccuracies.
    If you have received this program by means other than downloading, the
    newest version with C source code should be available at http://WXTide32.com

    The tide prediction algorithm used in this program was developed with United
    States Government funding, so no proprietary rights can be attached to it

    Many thanks to Hans Pieper, the author of the DOS Tide 2.4 program, for
    allowing me to include the subordinate station data from his program for
    about 5000 locations worldwide. His program with the subordinate station data
    files can be found on the web by searching for "tide24".


Manual installation
~~~~~~~~~~~~~~~~~~~
The distribution has a small setup program and inf file that will install the
program and start menu entries but the same can easily be performed manually.

Unzip all files into a clean folder, usually "c:\program files\wxtide32\".
After unzipping make a shortcut to WXTide32 by dragging "WXTide32.exe" from the
install folder to the desktop. If error messages appear when the program is run
the first time, make sure the "working folder" entry in the shortcut properties
shortcut tab points to the folder in which the program resides. This is the
default and should not be a problem.


Manual uninstall
~~~~~~~~~~~~~~~~~~~
WXTide32 does NOT modify the registry or change any files outside of it's home
folder. After a manual install it is safe to delete all install files and folder.


Files included in the distribution
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
readme.txt   This file
gpl          General Public License (please read, IT IS IMPORTANT)
WXTide32.exe Win9x/NT 32 bit executable
WXTide32.cfg Configuration file for WXTide32
WXTide32.hlp On-line help file
WXTide32.cnt Help file index
harmonic     XTide harmonic constants file
harmonic.msc XTide harmonic constants file, misc locations
harmonic.idx Station index for harmonic constants file
WXTSrc##.7z  Source files for WXTide32 where "##" is the version number.


Source files
~~~~~~~~~~~~
The file WXTidSrc##.7z has all the source code for the WXTide32 program. Three
files: Tide2idx.c, Tide2idx.ctl and tide2idx.bat form the station index builder
DOS console executable. For tide2idx.bat to work properly, the "subreg" path will
have to be changed to point to the Tide 2.4 subreg files.


Station indexing
~~~~~~~~~~~~~~~~
The Tide2IDX program generates a sortable station index from one or more
harmonic constituent and subordinate station files.  I never was very good with
geography and as I HAVE NO INTEREST IN POLITICS, political boundary
assignments may seem arbitrary to some extent.  So if you don't like the
region/country/state that your station appears in, try changing the
Tide2IDX.ctl file and make a new index. To generate a new index with
subordinate stations, you must download and unzip the Tide24 program mentioned
earlier.  The files of interest are in the subdirectory "substa" and are all
called "subreg.xx" where "xx" is a region number.  The "makeidx.bat" file
builds an index including all the "substa" files. You will have to change the
search path in makeidx.bat to point to those files for it to work properly.


Binary TCD files
~~~~~~~~~~~~~~~~
WXTide32 version 4.2 adds the ability to read binary TCD format tide files.
These files are smaller and faster than previous ASCII text files.  Originally
written by Jan Depner to support requirements of the U.S. Naval Oceanographic
Office (NAVO), the library API and files are now maintained by Dave Flater.
See libtcd.html (enclosed) for additional information.

Limitations of the WXTide32 implementation of libtcd and TCD files:
1) There is no support for updating or writing to the database.
2) Newer TCD files span years 1700-2099 but WXTide32 limits span to 1970-2038.
3) Slack Current time offsets are ignored; capability will be added later.
4) No support for displaying restriction, comments, or notes fields.
5) Leagalese text (if any) displays when station is selected

           Added conversion of special characters.

           Corrected Tide2Idx making wrong substation Lat/Lon occasionally.
           Corrected and added several index reference station assignments.

           Added an alternate form to -hloff and -lloff tide level switches:

           Index now includes 361 new subordinate stations with both level
                multipliers and offsets that previously could not be used.
           NOTE: !!!Index file format has changed!!!  Version 2.0 will not work
                with index files from previous versions.

Ver 1.3    Made Save menu option grey out when no changes have been made.
1998/03/10 Added online-help (I hope it was worth all that typing).

                offsets (time or level or multiplier) were identical.
           Removed "Save windows with configuration" switch since that was only
                for testing and was not supposed to be in the released version.

                with extra switches.  Previously, if a config file name was
                passed as the first parameter, then no additional switches
                could be specified.
           Added -numdays switch (Preferences menu).

                start with the options in that configuration file.
           Changed name of Flags to Preferences.
           Reorganized Preferences and added:
                -units    - Conversion of units to feet or meters.
                -autokt   - Auto conversion of knots^2 to knots. (Finally!)
                -gstretch - was only a command line switch, now interactive.
                -autosave - Enables changes to options to be automatically saved
                       to the configuration file on exit. Otherwise, you will
                       be prompted to save when exiting after changes.
                -windows  - Save window positions too when saving configuration.
                -moon     - Show moon phases on graphics screens.

           Cleaned up more focus problems.
           Disabled OFFSETSTEXTONLY abort.
           Added logic such that if a station name entered by the -location
                switch is not present, the program will start up with the
                location dialog to allow you to pick one from the list.
           Separated Background color into Day and Night backgrounds to give a
                more visual indication of day boundaries.
           Slight format changes to text tides and calendar output.
           Added pop-up information block when either button is clicked inside
                the main graphics screen showing time, date, and level under
                the pointer and astronomical (sun/moon) data.
           Corrected "Start date.." to begin at midnight on date selected.

(Ver 1.1)  Started using version numbers. Current version is 1.1
1998/02/10 Fixed "-units" switch.
           Made "-location" name on command line case insensitive. Also made any

           Added Help->About pulldown menu to get the current version.
           Cleaned up several window focus problems.

           Reduced default "-graph" mode width to 640 (was 960).
           Corrected error where changing from current station to tidal station
                did not change to levels from currents.
           Fixed Text Tide output so that current text output shows slack water
                in all modes, not just hairy mode.
           Added hourglass cursor while loading data files.
           Added invalid switch error message output on start-up.
