PN72039: ABEND013-20 CAN OCCUR IN ASMA90 WHEN SYSPRINT BLKSIZE=121 USED. SIMILAR PROBLEMS CAN OCCUR ON SYSTERM. SYSLIB PROBLEM ON CMS.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When //SYSPRINT DD DCB=BLKSIZE=121 is specified and LRECL=121
  is not specified the assembler assumes LRECL=133 and an ABEND
  013-20 results on OPEN of SYSPRINT.
  ABEND013-34 possible when SYSTERM DD allocated to DASD but no
  DCB parameters specified.
  Incorrect SYSLIB DSN information can occur in the Macro and Copy
  Cross Reference listing when a SYSLIB FILEDEF is allocated to
  several OS PDSs but the first is a non-existant dataset.
  It is also possible to get truncated displacements in the
  Active Usings heading.
  

Local fix

• Either:
  1) do not specify BLKSIZE= on the SYSPRINT dataset, or,
  2) specify LRECL= with the same value as BLKSIZE= on the DD.
  3) for SYSTERM DD to DASD, specify DCB=(RECFM=FB,LRECL=121)
  4) for SYSLIB from CMS to multiple OS MACLIBs, make sure that
     all DSNs exist on the linked DASD.

  ****************************************************************
  The DCB OPEN exit for SYSPRINT sets a default value of 133 for
  LRECL if no LRECL is specified in the DCB information for the
  SYSPRINT dataset.  This is fine if BLKSIZE is not specified.
  However, if the JCL has a BLKSIZE specification on the SYSPRINT
  dataset and it is not 133 (or a multiple of 133 if the file is
  blocked) then the OPEN is terminated with ABEND S013 reason code
  20 (or an equivalent under CMS).  This is because the LRECL and
  BLKSIZE are incompatible.  Under MVS MSGIEC141I is also issued.
  Similar errors can occur on SYSTERM.
  
  There is a known problem in VM/CMS's handling of BPAM emulation
  on concatenated SYSLIB datasets where OS PDSs are involved.
  
  The service level (PTF) information is printed too late in some
  circumstances to be helpful.  Option warnings are not noted in
  the "NO STATEMENTS FLAGGED IN THIS ASSEMBLY" message on
  SYSPRINT.
  

Problem conclusion

• The DCB OPEN exit for SYSPRINT will be improved to ensure that
  BLKSIZE, LRECL and RECFM have reasonable values in the DCB open
  exits for SYSPRINT and SYSTERM (MVS and CMS only).
  
  VM APAR VM59591 can be applied if problems are found with the
  names of OS PDS datasets in the MACRO AND COPY CROSS REFERENCE
  portion of the listing.
  
  The service level (PTF) of the assembler will now be shown in
  the heading of the Options Summary as well as in its current
  location on the last page of the listing.
  
  The string "OPTION WARNING(S) WERE ISSUED" will appear after
  "... STATEMENTS FLAGGED IN THIS ASSEMBLY" in the listing if
  option warnings were issued in the option summary.
