ソースファイルは、その拡張子（.pas）で指定する必要があります。
XD Pascalは、Delphi 6/7およびFree Pascalに似ています。
Textタイプはfileと同等です。テキストファイルとUntypedファイルの両方に使用できますExtended Doubleに相当しますHighおよびLow機能はありません。オープン配列の長さは明示的にサブルーチンに渡す必要があります ProgramOrUnit = [("program" | "unit") Ident ";"]

コンパイラは、再帰降下パーサーに基づいています。外部アセンブラーまたはリンカーを使用せずに、Windows PE実行可能ファイルを直接構築します。
$APPTYPEアプリケーションタイプを設定します。例： {$APPTYPE GUI} 、 {$APPTYPE CONSOLE}$UNITPATH追加のユニット検索パスを設定します。例： {$UNITPATH ..units} いくつかの単純な剥離最適化が実行されます：
コンパイラの一部として、次の識別子が実装されています。彼らの名前は予約された単語ではなく、ユーザーがローカルに再定義することができます。
