// How to add the Calendar to your page:
//            This script needs to be defined for your page so, immediately
//            after the BODY tag add the following line;
//
//                  <script type='Text/JavaScript' src='scw.js'></script>
//
//            Your root directory of the web site should also contain an empty
//            file called "scwblank.html". See
//                  http://www.tarrget.info/calendar/IEnightmare.html
//            for a full explanation.
//
// How to use the Calendar once it is defined for your page:
//
//            Simply choose an event to trigger the calendar (like an onClick
//            or an onMouseOver) and an element to work on (for the calendar
//            to take its initial date from and write its output date to) then
//            write it like this;
//
//                  <<event>>="scwShow(<<element>>,event);"
//
//            e.g. onClick="scwShow(scwID('myElement'),event);"
//            or   onMouseOver="scwShow(this,event);"
//
//            NOTE: If you wish to use the calendar with an Anchor tag, do
//                  not use the syntax:   href="javascript:scwShow(...)"
//                  Instead you should use the following;
//
//                  <a href="#" onclick="scwShow(<<element>>,event);return false;">
//                      <<your text>>
//                  </a>
//
//            If you are using a text node then specify the text's parent node
//            in the function call. The date should be the only text under that
//            node;
//
//            e.g.  <p onclick="scwShow(this,event);"><<date>></p>
//
//            You can also disable days of the week by adding arguments to the
//            call to scwShow.  The values should be Sunday = 0 through to
//            Saturday = 6.  A call to scwShow with Friday and Monday disabled
//            would look something like this;
//
//                  scwShow(<<element>>,event,5,1);
//
//            Finally you can use the following technique to run a function
//            when the calendar closes:
//
//                  scwNextAction=<<function>>.runsAfterSCW(this,<<arguments>>);
//                  scwShow(<<element>>,event <<,optional arguments above>>);
//
//            Where <<function>> is a function defined on the calling page
//            and <<arguments>> is the list of arguments being passed to that
//            function.
//
//            ------------------------------------------------------------------
//            Here's an extremely trivial but fully functioning example page
//            showing two of the ways to trigger the calendar;
//
//            <html>
//                <head><title>Basic Example</title></head>
//                <body>
//                    <script type='text/JavaScript' src='scw.js'></script>
//                    <p onclick='scwShow(this,event);'>06-Dec-2006</p>
//                    <input onclick='scwShow(this,event);' value='07-Dec-2006' />
//                    <br/><br/>
//                    <a href='#' onclick='scwShow(this,event);return false;'>
//                        08-Dec-2006
//                    </a>
//                </body>
//            </html>

// =======   ====        ===============  ===========
//   3.58    2007-04-04  Anthony Garrett  Resolved an error caused when the date
//                                         range does not include the current year.
//                                         Thanks to Steve Davis for letting me know.
//
//                                        Fixed "Today" selector display which
//                                         was incorrectly visible when year range
//                                         ended last year. (Also the result of
//                                         investigations based on Steve Davis'
//                                         feedback).
//
//   3.59    2007-06-13  Anthony Garrett  Added Verdana to font list of
//                                         calendar's CSS.  Resolves rendering
//                                         bug in Safari Beta 3 for Windows.
//
//   3.60    2007-07-31  Anthony Garrett  Fixed javascript error that occurred
//                                         when the target element had no value
//                                         attribute.  The error had no impact
//                                         on the behaviour of the script.  Thanks
//                                         to John Phelps for reporting this bug.
//
//   3.70    2007-09-21  Anthony Garrett  Updated the event trapping to make it
//                                         less intrusive on the page body.
//                                         NOTE: This requires that a calendar's
//                                         second parameter should be the calling
//                                         event (not the calling object as in
//                                         previous versions).
//                                         Thanks to Steve Davis for the bug report
//                                         that led to this change.
//
//                                        Fixed a bug that caused undelimited
//                                         dates to be handled incorrectly. They
//                                         are now parsed against the full date
//                                         output format then checked for validity.
//                                         Thanks to Dan Wood for raising this bug.
//
//                                        Replaced the date input sequence user
//                                         configuration setting with parsing the
//                                         sequence from the full format. New users
//                                         are often confused by the sequence and
//                                         in practice (to allow the calendar's date
//                                         output to be used for input) the sequence
//                                         must always match the full format element
//                                         order.
//
//                                        Extended IFRAME backing to all calendar objects
//                                         in order to improve calendar display over
//                                         some embedded applets and objects.  Thanks to
//                                         Stanko Kupcevic for his feedback on this.
//                                         NOTE: It is not possible to protect any
//                                         JavaScript object displayed over an
//                                         embedded DYNAMIC (and, therefore refreshed)
//                                         object because browsers usually do not
//                                         directly control the screen handling within
//                                         the object.  The best advice therefore remains
//                                         to design pages in such a way that the calendar
//                                         does not overlap embedded objects.

// The above approach will allow you to disable days of the week
// for the whole of your page easily.  If you need to set different
// disabled days for a number of date input fields on your page
// there is an easier way: You can pass additional arguments to
// scwShow. The syntax is described at the top of this script in
// the section:
//    "How to use the Calendar once it is defined for your page:"
//
// It is possible to use these two approaches in combination.

// You can disable any specific date (e.g. 24-Jan-2006 or Today) by

var scwOutOfMonthDisable = false;
var scwOutOfMonthHide    = false;

// Dates that are out of the specified range can be displayed at the start
// of the very first month and end of the very last.  Set

// allow their selection).

// You can allow the calendar to be dragged around the screen by

// I can't say I recommend it because of the danger of the user
