You can show the value of internal table as editor in ABAP/4 editor and you can modify data too by applying EDITOR-CALL statement.

Example

DATA: BEGIN OF itab occurs 0,
        text(100),
      END OF itab.
INITIALIZATION.
  itab-text = ’Line1: ’.
  APPEND itab.
  itab-text = ’Line2: ’.
  APPEND itab.
  itab-text = ’Line3: ’.
  APPEND itab.
  itab-text = ’Line4: ’.
  APPEND itab.
START-OF-SELECTION.
  EDITOR-CALL FOR itab TITLE ’Testing EDITOR-CALL for internal table’.
  LOOP AT itab.
    WRITE:/ itab-text.
  ENDLOOP.

The output is:

• When you execute program
  
  
• You can modify the data in your internal table
  
  
• You can confirm your data by select . System will show the data that already contained in internal table as ABAP list report.
