NAME

       OLE::Storage_Lite - Simple Class for OLE document interface.

SYNOPSIS

	   use OLE::Storage_Lite;

	   # Initialize.

	   # From a file
	   my $oOl = OLE::Storage_Lite->new("some.xls");

	   # From a filehandle object
	   use IO::File;
	   my $oIo = new IO::File;
	   $oIo->open("<iofile.xls");
	   binmode($oIo);
	   my $oOl = OLE::Storage_Lite->new($oFile);

	   my $oPps = $oOl->getPpsTree(1);

	   # Save Data
	   # To a File
	   $oPps->save("kaba.xls"); #kaba.xls
	   $oPps->save('-');	    #STDOUT

	   # To a filehandle object

	   bimode($oIo);
	   $oPps->save($oIo);

DESCRIPTION

       OLE::Storage_Lite allows you to read and write an OLE structured file.

       OLE::Storage_Lite::PPS is a class representing PPS. OLE::Storage_Lite::PPS::Root, OLE::Storage_Lite::PPS::File and
       OLE::Storage_Lite::PPS::Dir are subclasses of OLE::Storage_Lite::PPS.

   new()
       Constructor.

	   $oOle = OLE::Storage_Lite->new($sFile);

       Creates a OLE::Storage_Lite object for $sFile. $sFile must be a correct file name.

       The "new()" constructor also accepts a valid filehandle. Remember to "binmode()" the filehandle first.

   getPpsTree()
	   $oPpsRoot = $oOle->getPpsTree([$bData]);

       Returns PPS as an OLE::Storage_Lite::PPS::Root object.  Other PPS objects will be included as its children.

       If $bData is true, the objects will have data in the file.

   getPpsSearch()
	   $oPpsRoot = $oOle->getPpsTree($raName [, $bData][, $iCase] );

       Returns PPSs as OLE::Storage_Lite::PPS objects that has the name specified in $raName array.

       If $bData is true, the objects will have data in the file.  If $iCase is true, search is case insensitive.

   getNthPps()
	   $oPpsRoot = $oOle->getNthPps($iNth [, $bData]);

       Returns PPS as "OLE::Storage_Lite::PPS" object specified number $iNth.

       If $bData is true, the objects will have data in the file.

   Asc2Ucs()
	   $sUcs2 = OLE::Storage_Lite::Asc2Ucs($sAsc>);

       Utility function. Just adds 0x00 after every characters in $sAsc.

   Ucs2Asc()
	   $sAsc = OLE::Storage_Lite::Ucs2Asc($sUcs2);

       Utility function. Just deletes 0x00 after words in $sUcs.

OLE
::Storage_Lite::PPS
       OLE::Storage_Lite::PPS has these properties:

       No  Order number in saving.

       Name
	   Its name in UCS2 (a.k.a Unicode).

       Type
	   Its type (1:Dir, 2:File (Data), 5: Root)

       PrevPps
	   Previous pps (as No)

       NextPps
	   Next pps (as No)

       DirPps
	   Dir pps (as No).

       Time1st
	   Timestamp 1st in array ref as similar fomat of localtime.

       Time2nd
	   Timestamp 2nd in array ref as similar fomat of localtime.

       StartBlock
	   Start block number

       Size
	   Size of the pps

       Data
	   Its data

       Child
	   Its child PPSs in array ref

OLE
::Storage_Lite::PPS::Root
       OLE::Storage_Lite::PPS::Root has 2 methods.

   new()
	   $oRoot = OLE::Storage_Lite::PPS::Root->new(
			   $raTime1st,
			   $raTime2nd,
			   $raChild);

       Constructor.

       $raTime1st, $raTime2nd are array refs with ($iSec, $iMin, $iHour, $iDay, $iMon, $iYear).  $iSec means seconds, $iMin means minutes. $iHour
       means hours.  $iDay means day. $iMon is month -1. $iYear is year - 1900.

       $raChild is a array ref of children PPSs.

   save()
	   $oRoot = $oRoot>->save(
			   $sFile,
			   $bNoAs);

       Saves information into $sFile. If $sFile is '-', this will use STDOUT.

       The "new()" constructor also accepts a valid filehandle. Remember to "binmode()" the filehandle first.

       If $bNoAs is defined, this function will use the No of PPSs for saving order.  If $bNoAs is undefined, this will calculate PPS saving
       order.

OLE
::Storage_Lite::PPS::Dir
       OLE::Storage_Lite::PPS::Dir has 1 method.

   new()
	   $oRoot = OLE::Storage_Lite::PPS::Dir->new(
			   $sName,
			 [, $raTime1st]
			 [, $raTime2nd]
			 [, $raChild>]);

       Constructor.

       $sName is a name of the PPS.

       $raTime1st, $raTime2nd is a array ref as ($iSec, $iMin, $iHour, $iDay, $iMon, $iYear).  $iSec means seconds, $iMin means minutes. $iHour
       means hours.  $iDay means day. $iMon is month -1. $iYear is year - 1900.

       $raChild is a array ref of children PPSs.

OLE
::Storage_Lite::PPS::File
       OLE::Storage_Lite::PPS::File has 3 method.

   new
	   $oRoot = OLE::Storage_Lite::PPS::File->new($sName, $sData);

       $sName is name of the PPS.

       $sData is data of the PPS.

   newFile()
	   $oRoot = OLE::Storage_Lite::PPS::File->newFile($sName, $sFile);

       This function makes to use file handle for geting and storing data.

       $sName is name of the PPS.

       If $sFile is scalar, it assumes that is a filename.  If $sFile is an IO::Handle object, it uses that specified handle.  If $sFile is undef
       or '', it uses temporary file.

       CAUTION: Take care $sFile will be updated by "append" method.  So if you want to use IO::Handle and append a data to it, you should open
       the handle with "r+".

   append()
	   $oRoot = $oPps->append($sData);

       appends specified data to that PPS.

       $sData is appending data for that PPS.

CAUTION

       A saved file with VBA (a.k.a Macros) by this module will not work correctly.  However modules can get the same information from the file,
       the file occurs a error in application(Word, Excel ...).

DEPRECATED FEATURES

       Older version of "OLE::Storage_Lite" autovivified a scalar ref in the "new()" constructors into a scalar filehandle. This functionality is
       still there for backwards compatibility but it is highly recommended that you do not use it. Instead create a filehandle (scalar or
       otherwise) and pass that in.
