CASL2, COMET2 の JavaScript 実装です． オリジナルの perl 版は https://github.com/omzn/casl2

• 開く Web ページ

• 状況: stable
  • jqueryterminal.js を利用して，Web ページ上の簡易ターミナルで動かすようにした． CLIインタラクティブインターフェイスがそのまま利用できる．
  • CASL2のテキストエリアにファイルをドラッグアンドドロップできるようになった．

• 状況: stable

Usage: c2c2 [options] <casl2file> [input1 ...]

Options:
  -V, --version   output the version number
  -a, --all       [casl2] show detailed info
  -c, --casl      [casl2] apply casl2 only
  -r, --run       [comet2] run immediately
  -n, --nocolor   [casl2/comet2] disable color messages
  -q, --quiet     [casl2/comet2] be quiet
  -Q, --QuietRun  [comet2] be QUIET! (implies -q and -r)
  -h, --help      display help for command

• ブラウザ版と基本的な動作は同じなので，動作確認にはこちらを使った方が早い．

$ node c2c2 -n -r -q caslfile.cas

とすると，入出力のプロンプト以外の出力は抑制され(-q)，文字色は取り除かれ(-n)，プログラムをアセンブル後，すぐに実行が始まる(-r)． また，動作確認などのため，あらかじめIN> に渡すべき入力をファイル名以降の[input ...]に記述できる．

• ラベルにはスコープがあります．スコープはプログラム内(START 命令から END 命令で囲まれた部分)のみです．
• CALL 命令にもスコープが効きますが，CALL だけは別プログラムの開始ラベル(START 命令のラベル)まで参照できます．
• 簡単のため，MULA (算術乗算), MULL (論理乗算), DIVA (算術除算), DIVL (論理除算)を実装しています．利用方法は ADDA, ADDL 等とほぼ同じです．
• DC 命令で文字列を確保すると，最後に0(ヌル文字)が1文字追加されます．(文字列の終わりを容易に判定するため)
• ラベルは「英大文字，英小文字，$, _, %, . 」のいずれかで始まり，「英大文字，英小文字，数字，$, _, %, . 」を含む長さ制限の無い文字列で表します．
• ラベルのみの行を許容します．

• DIVA, DIVL については，0 除算を行おうとすると ZF と OF が同時に立って，メッセージを表示した後，プログラムは停止します．
