  Cannot to lock data file.
  Too heavy writing request?

<p>
  Another reason, Under maintenance?
</p>
<p>
  Sometime later, try to write again.
</p>
<p>
  書き込み要求が集中してしまって,
  データファイルをロックできなかったのが原因だと思われます.
</p>
<p>
  もうひとつの可能性として,
  管理者がメンテナンスのために
  意図的にデータのあるディレクトリへの書き込みを禁止している
  ということが考えられます.

<p>
  どっちにしても,もう少し待って書き込んでみてください.

  DIV要素(&lt;div&gt; 〜 &lt;/div&gt;)と
  テーブルのセル要素(&lt;td&gt; 〜 &lt;/td&gt;)

  ただし,保安上の都合やWebブライザどうしの互換性の問題等のために,
  <strong>次のタグは使用できない</strong>ようにしています.

# HTML tag check for posting BBS article
# written by yav <yav@bigfoot.com>
#
# 概要:
# BBSに投稿する記事がHTMLの文書定義に従っているかを確認するスクリプトです.
# ただし,プログラム簡略化のため,
# 単に使用可能なタグかどうかをチェックしてるだけです.
# 使用可能かどうかの判断はW3Cの文書型定義を参考にしています.
# 属性値はクォートの確認だけで,あとはほとんどノーチェックです.
# また,本来は省略可とされてるタグも省略できません.
# Sample document 1: これはダメです!
#   <dl>
#     <dt>DTD<dd>Document Type Definition
#     <dt>HTML<dd>Hyper Text Mark-up Language
#   </dl>
# Sample document 2: こう書いてください
#   <dl>
#     <dt>DTD</dt><dd>Document Type Definition</dd>
#     <dt>HTML</dt><dd>Hyper Text Mark-up Language</dd>
#   </dl>
#
#
# 使い方:
# チェックしたいテキストが$textに入ってるとしたら,
# @errors = &htmlck'report($text, 'p');
# というように最初の引数にソレを指定してreportをコールします.
# 2番目の引数はそのテキストがどんなタグ(正確には要素)の中に
# 入ってるものとしてチェックするかです.
# 通常,BBSの記事は<p>か<div>もしくは<td>の中に入って表示されると思いますが,
# たとえば,<p>で囲んで表示する場合には
# @errors = &htmlck'report($text, 'p');
# とやって,<p>の中に入ってるものとしてチェックします.
#
# もし構文的に問題があれば,
# 与えられたテキストを誤った部分と正しい部分に分解したリストを返します.
# たとえば,"<bad>Bad</bad>"をチェックすると,
# ("1<bad>", "0Bad", "1</bad>") というリストが返されると思います.
# もしエラーが何もなければ,空のリストが返されます.
#
# 通常は HTML-3.2 としてチェックしますが,
# &htmlck'html_version('4.01 Transitional');
# のように html_versionをコールすると
# HTML-4.01としてチェックするようになります.
# いまのとこ,'3.2'と'4.01'しか対応してません.
#
# 具体的な使い方は↓のサンプルプログラムを見てください.
#
# Sample program:
#   require "jcode.pl";
#   require "htmlck.pl";
#   @data = <>;
#   $_ = join("", @data);
#   &jcode'convert(*_, 'euc');	# '
#   &htmlck'html_version('4.01 Transitional');	# ' '4.01' or '3.2'(default)
#   @list = &htmlck'report($_, 'body');	# '
#   foreach (@list) {
#       ($f, $_) = split(//, $_, 2);
#       s/&/&amp;/g;
#       s/</&lt;/g;
#       s/>/&gt;/g;
#       $_ = "<font color=red>$_</font>" if $f;
#   }
#   $_ = join("", @list);
#   &jcode'convert(*_, 'sjis');	# '
#   print;
#   exit 0;
#

;# PERL4 INTERFACE:
;#
;#	&jcode'getcode(*line)
;#		Return 'jis', 'sjis', 'euc' or undef according to
;#		Japanese character code in $line.  Return 'binary' if
;#		the data has non-character code.
;#
;#		When evaluated in array context, it returns a list
;#		contains two items.  First value is the number of
;#		characters which matched to the expected code, and
;#		second value is the code name.  It is useful if and
;#		only if the number is not 0 and the code is undef;
;#		that case means it couldn't tell 'euc' or 'sjis'
;#		because the evaluation score was exactly same.  This
;#		interface is too tricky, though.
;#
;#		Code detection between euc and sjis is very difficult
;#		or sometimes impossible or even lead to wrong result
;#		when it includes JIS X0201 KANA characters.  So JIS
;#		X0201 KANA is ignored for automatic code detection.
;#
;#	&jcode'convert(*line, $ocode [, $icode [, $option]])
;#		Convert the contents of $line to the specified
;#		Japanese code given in the second argument $ocode.
;#		$ocode can be any of "jis", "sjis" or "euc", or use
;#		"noconv" when you don't want the code conversion.
;#		Input code is recognized automatically from the line
;#		itself when $icode is not supplied (JIS X0201 KANA is
;#		ignored in code detection.  See the above descripton
;#		of &getcode).  $icode also can be specified, but
;#		xxx2yyy routine is more efficient when both codes are
;#		known.
;#
;#		It returns the code of input string in scalar context,
;#		and a list of pointer of convert subroutine and the
;#		input code in array context.
;#
;#		Japanese character code JIS X0201, X0208, X0212 and
;#		ASCII code are supported.  X0212 characters can not be
;#		represented in SJIS and they will be replased by
;#		"geta" character when converted to SJIS.
;#
;#		See next paragraph for $option parameter.
;#
;#	&jcode'xxx2yyy(*line [, $option])
;#		Convert the Japanese code from xxx to yyy.  String xxx
;#		and yyy are any convination from "jis", "euc" or
;#		"sjis".  They return *approximate* number of converted
;#		bytes.  So return value 0 means the line was not
;#		converted at all.
;#
;#		Optional parameter $option is used to specify optional
;#		conversion method.  String "z" is for JIS X0201 KANA
;#		to X0208 KANA, and "h" is for reverse.
;#
;#	$jcode'convf{'xxx', 'yyy'}
;#		The value of this associative array is pointer to the
;#		subroutine jcode'xxx2yyy().
;#
;#	&jcode'to($ocode, $line [, $icode [, $option]])
;#	&jcode'jis($line [, $icode [, $option]])
;#	&jcode'euc($line [, $icode [, $option]])
;#	&jcode'sjis($line [, $icode [, $option]])
;#		These functions are prepared for easy use of
;#		call/return-by-value interface.  You can use these
;#		funcitons in s///e operation or any other place for
;#		convenience.
;#
;#	&jcode'jis_inout($in, $out)
;#		Set or inquire JIS start and end sequences.  Default
;#		is "ESC-$-B" and "ESC-(-B".  If you supplied only one
;#		character, "ESC-$" or "ESC-(" is prepended for each
;#		character respectively.  Acutually "ESC-(-B" is not a
;#		sequence to end JIS code but a sequence to start ASCII
;#		code set.  So `in' and `out' are somewhat misleading.
;#
;#	&jcode'get_inout($string)
;#		Get JIS start and end sequences from $string.
;#
;#	&jcode'cache()
;#	&jcode'nocache()
;#	&jcode'flush()
;#		Usually, converted character is cached in memory to
;#		avoid same calculations have to be done many times.
;#		To disable this caching, call &jcode'nocache().  It
;#		can be revived by &jcode'cache() and cache is flushed
;#		by calling &jcode'flush().  &cache() and &nocache()
;#		functions return previous caching state.
;#
;#	---------------------------------------------------------------
;#
;#	&jcode'h2z_xxx(*line)
;#		JIS X0201 KANA (so-called Hankaku-KANA) to X0208 KANA
;#		(Zenkaku-KANA) code conversion routine.  String xxx is
;#		any of "jis", "sjis" and "euc".  From the difficulty
;#		of recognizing code set from 1-byte KATAKANA string,
;#		automatic code recognition is not supported.
;#
;#	&jcode'z2h_xxx(*line)
;#		X0208 to X0201 KANA code conversion routine.  String
;#		xxx is any of "jis", "sjis" and "euc".
;#
;#	$jcode'z2hf{'xxx'}
;#	$jcode'h2zf{'xxx'}
;#		These are pointer to the corresponding function just
;#		as $jcode'convf.
;#
;#	---------------------------------------------------------------
;#
;#	&jcode'tr(*line, $from, $to [, $option])
;#		&jcode'tr emulates tr operator for 2 byte code.  Only 'd'
;#		is interpreted as an option.
;#
;#		Range operator like `A-Z' for 2 byte code is partially
;#		supported.  Code must be JIS or EUC, and first byte
;#		have to be same on first and last character.
;#
;#		CAUTION: Handling range operator is a kind of trick
;#		and it is not perfect.  So if you need to transfer `-' 
;#		character, please be sure to put it at the beginning
;#		or the end of $from and $to strings.
;#
;#	&jcode'trans($line, $from, $to [, $option)
;#		Same as &jcode'tr but accept string and return string
;#		after translation.
;#
;#	---------------------------------------------------------------
;#
;#	&jcode'init()
;#		Initialize the variables used in this package.  You
;#		don't have to call this when using jocde.pl by `do' or
;#		`require' interface.  Call it first if you embedded
;#		the jcode.pl at the end of your script.
