  * RECOMMENDATION: Apply the maintenance for this APAR.         *
  ****************************************************************
  This APAR provides new option keyword, REFER_PSB=YES|NO, for
  decoding condition that specifies whether to refer to a PSB-type
  ACB when the utility decodes an ACB for DEDB or MSDB.
  
  When the DBD/PSB/ACB Reversal utility or Catalog Manager utility
  decodes an ACB for a DEDB or MSDB, a PSB-type ACB that
  references the ACB is used for obtaining the DBD VERSION or EXIT
  parameter value because DBD-type ACB does not have this value.
  
  When the target library has many members, it can be
  time-consuming to obtain these values. You can specify whether
  the utility skips this process to obtain these values. When the
  utility skips this process to obtain these parameter values,
  warning message FABN0077W is issued in the decoded source and
  the SYSOUT dataset or the message report.
  
  The DBD/PSB/ACB Reversal utility and Catalog Manager utility can
  use this option. The default value is YES and the utility
  supplies these values from PSB-type ACB.
  
  This APAR also fixes the Advanced ACBGEN to process all of the
  members specified in the SYSIN statement even when a large
  number of members are specified in the SYSIN statement.
  
  The Advanced ACBGEN missed to store all of the specified members
  if a large number of members are specified in the SYSIN
  statement.
  This APAR fixes to process all of the members specified in the
  SYSIN statement. The digit number RCD# that are written in the
  CONTENTS OF "SYSIN   " CONTROL STATEMENT DATASET of the INPUT
  SPECIFICATIONS report has been increased by one digit.
  
  This APAR also improves the performance of the function for IMS
  Administration Tool.
