تُظهر لقطة الشاشة التالية دفق الكتل الناتج:
[عفا عليها الزمن] يمكن أيضًا "فتح" تيار الكتلة لإظهار تيار الرموز داخل كل كتلة. يظهر هذا في لقطة الشاشة التالية:
يتم تحويل دفق الكتل من الخطوة 2 إلى تيار من المجموعات.
يمكن أن تكون واحدة من العديد من خطوات معالجة ما بعد المعالجة هي إزالة المساحات البيضاء والمسافة البادئة والتعليقات. لذلك يمكن تطبيق مرشح لإزالة هذه أنواع الحظر. بالإضافة إلى ذلك ، يمكن دمج الكتل المتعددة (على سبيل المثال إذا تم إدراج تعليق أو خط خط بين تسلسل التعليمات البرمجية المتتالية ، والتي تنتمي إلى كتلة واحدة) إلى كتلة واحدة.
