  This APAR fixes Advanced ACBGEN not to end with ABENDS337 or
  ABENDS0C1.
  The problem is caused when all of the following conditions met.
  1. BUILD DBD=dbdname,BLDPSB=NO is specified for a Fast Path
     database.
  2. PRECOMP is specified in a parameter field in the EXEC
     statement.
  3. DBD type ACB is moved in data set by compression process.
  
  Advanced ACBGEN caches TTR value for each ACB members which
  indicates a offset of a member in the ACBLIB data set at first.
  Then compression process runs before ACBGEN process when
  PRECOMP parameter is specified. If ACB is moved in the data set
  by the compression process, its TTR value is changed and
  inconsistent with the cache. When BUILD DBD=dbdname,BLDPSB=NO
  is specified for a Fast Path database, Advanced ACBGEN
  accesses the DBD type ACB with the incorrect cached TTR value
  and it causes the ABEND.
  This APAR fixes Advanced ACBGEN to avoid the ABEND by updating
  cached TTR value.
