IO26200: ABEND S0CB (DIVIDE BY ZERO) IN GIMZIP FOR A DATA SET WITH BLKSIZE=0

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• GIMZIP fails with ABEND S0CB (divide by zero) when it processes
  a data set that has a zero block size.  For example, allocate a
  data set like this:
  
  //ALLOC    EXEC PGM=IEFBR14
  //SMPLOGA  DD DSN=userid.TEST.SMPLOGA,DISP=(NEW,CATLG),
  //            UNIT=SYSALLDA,SPACE=(CYL,(1,1)),
  //            RECFM=VB,BLKSIZE=0
  
  The GIMZIP service routine will end with ABEND S0CB as it
  attempts to process the subject data set.
  

Local fix

• As a circumvention, ensure data sets to be processed by GIMZIP
  have a non-zero block size.

  ****************************************************************
  During processing, the GIMZIP service routine attempts to obtain
  the current attributes (including the current space allocation)
  for the data sets being processed.  It attempts to convert the
  primary and secondary space allocations to AVGREC units which
  requires division by the blocksize.  When the blocksize is zero,
  this division results in an abend S0CB.
  

Problem conclusion

• Modules GIMMPDSA and GIMZPPRC have been modified in SMP/E 3.6 to
  allow the processing of a data set with a zero blocksize.
