  ****************************************************************
  HPCABAT0 does not ensure a MAXLOG RC value.  This leads to the
  job finishing with RC=0 and no HPC1310I message is issued even
  though the MAXIMUM LOGS threshold is met.
  HPCSBAT0 omits the syntax and use/meaning of MAXLGRC and this is
  not intuitive.
  When SYSPRINT DD is omitted HPCABAT0 dynamically allocates the
  SYSPRINT dataset.  The allocation parameters used in the SVC 99
  specify and incorrect block size.  The HPCABATO establishes the
  DCBEODA & DCBSYNA in the DSB based on register 4 which points to
  the DSB at the time it is built.  HPCALST0 later opens SYSPRINT
  for input and accesses the DSB with register 7.  EOD or I/O
  error conditions result in un-predictable AbEnds.
  

Problem conclusion

Temporary fix

Comments

• HPCABAT0 is changed to check for parameter MAXLOG
  RC=nn/MAXLGRC=nn if parameter MAXIMUM LOGS=nnn/MAXLOGS=nnn is
  specified.  If MAXIMUM LOGS=nnn/MAXLOGS=nnn is specified but
  MAXLOG RC=nn/MAXLGRC=nn is omitted, then default return code
  value 1 is set for MAXLOG RC=nn/MAXLGRC=nn.
  
  HPCSBAT0 in SHPCSAMP is updated to show the syntax and meaning
  of the MAXLGRC parameter.
  
  HPCAMAIN is changed to output the correct RC with the
  MAXLOGS/MAXLOG RC conditions are met.
  
  HPCABAT0 is changed to allocate SYSPRINT with an appropriate
  block size.
  
  HPCALST0 is changed to reference the SYSPRINT DSB with the
  correct register.
