// NAME
//
//  ALEntryList::ToggleMarks()
//
// PLATFORMS/ENVIRONMENTS
//
//  Console  Windows  PM
//  C++  C  VB  Delphi
//
// SHORT DESCRIPTION
//
//  Toggle the marks of every ALEntry object in a list.
//
// C++ SYNOPSIS
//
//  #include "arclib.h"
//
//  int ALEntryList::ToggleMarks();
//
// C SYNOPSIS
//
//  #include "arclib.h"
//
//  int ALEntryListToggleMarks( hALEntryList this_object );
//
// VB SYNOPSIS
//
//  Declare Function ALEntryListToggleMarks Lib "AL20LW"
//    (ByVal this_object&) As Integer
//
// DELPHI SYNOPSIS
//
//  function ALEntryListToggleMarks( this_object : hALEntryList ) : Integer;
//
// ARGUMENTS
//
//  this_object  :  A reference or pointer to the ALEntryList object that
//                  is going to be modified.  Note that the C++
//                  version of this function doesn't have an explicit argument
//                  here, since it has access to 'this' implicitly.
//
// DESCRIPTION
//
//  This simple member function just goes through the entire list,
//  toggling the mark state of every entry.  In other words, if the mark
//  was previously set, it will now be cleared, and vice versa.
//
// RETURNS
//
//  A count of the number of entries whose mark was changed.
//  (Just the total number of entries.)
//
// EXAMPLE

//
// REVISION HISTORY
//
//   November 13, 1995  2.00A : First release.
