  1. FPB DEDB Pointer Checker supports the checking of the segment
     length against the segment length definition.
  
  2. The following message texts have misspelled words.
     FABA4095E, FABC4095E, FABB0104I, and FABB0112E
  

Problem conclusion

Temporary fix

Comments

• FPB DEDB Pointer Checker verifies the segment length by the
  following method:
  
   The segment length value is verified whether it is in the range
   between the minimum length and the maximum length defined
   in DBD.
  
   In the case of SDEP segment,
   the length of the timestamp field attached at the end of SDEP
   data is not included in the LL value.
  
   In the case of the compressed segment,
   it is verified whether it is in between 3 and the maximum
   length added by 10.
  
   When DEDB Pointer Checker found the segment having the
   incorrect segment length, new FABA0168E message is issued and
   the DEDB Pointer Checker processing is continue without
   bypassing the CI containing the error.
  
  FABADBCI has been modified to add the checking of the ROOT/DDEP
  segment length.
  FABASDEP has been modified to add the checking of the SDEP
  segment length.
  Macro FABASEGL has been introduced to be embed above checking
  logic in both FABADBCI and FABASDEP.
  Macro FABUARCA has been modified to correct the misspelled word
  of FABA4095E and FABC4095E message texts.
  Macro ME1LTRL0 has been modified to correct the misspelled word
  of FABB0104I and FABB0112E message texts.

  Appendix O. FPB-messages and codes
    FABA messages
  
  The following message should be added as follows:
  
  FABA0168E SEGMENT AT RBA: xxxxxxxx (SEGCD: yy) HAS AN INVALID
            LENGTH OF SEGMENT
  
  Explanation: Program FABADA1 encountered a segment with an
  incorrect length during the serial "deblocking" of the CI.
  The length value is out of the range between the minimum length
  and the maximum length defined in DBD.
  If it is a compressed segment, it is out of the range and is
  in between 3 and the maximum length added by 10.
  System action: FABADA1 sets an end-of-job return code of 99,
  and continues processing.
  Programmer response: Correct any errors, and rerun the job.
  If this situation persists, report it to systems operations
  personnel.
