Exactly. What was  that language where you wrote  tags to indicate the
indenting of data structures:

      01  DREP.
          02  NO-REPR          PIC 9999.
          02  NO-SOTR          PIC 9999.
          02  NOM              PIC X(20).
          02  PRENOM           PIC X(15).
          02  A                PIC 9.
          02  B                PIC 9.
          02  FILLER           PIC X.
          02  D                PIC 9.
          02  FILLER           PIC X(33).
      01  DVTE.
          02  NO-SOTV          PIC 9999.
          02  NO-REPV          PIC 9999.
          02  MTV              PIC 9(6)V99.
          02  FILLER           PIC X(64).

Do not adjust your mind, there is a fault in reality.
