Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When a Generation Data Group is listed from FTP the member
  data sets may be listed out of sequence.  This can happen when
  the maximum record length on the catalog is altered from the
  default (and recommended) value of 32400 to a smaller size.
  VERIFICATION STEPS:  list the catalog with FTP and listcat
  and compare the result.

  * PROBLEM DESCRIPTION: A client enters a mput, mget or mdelete *
  *                      for a GDG and receives a prompt for the *
  *                      base group name. When creating the list *
  *                      of potential files, FTP includes files  *
  *                      that can not be processed.              *
  *                                                              *
  *                      User enters a DIR, LIST or NLST for a   *
  *                      block of GDS names and they are         *
  *                      returned out of sequence.               *

  ****************************************************************
  The FTP client issue a mput, mget or mdelete and receives a
  prompt for each item asking if it should be transferred or
  skipped. This list may contain items such as GDG base and VSAM
  files that FTP can not transfer or delete. If the client is a
  batch job, then FTP will attempt to transfer the object as a
  file and will fail.
  
  Some GDS files may be returned out of sequence when a dir
  list or nlst is issued from FTP.

Problem conclusion

• FTP has been changed such that a mput, mget or mdelete will only
  return a list of files that FTP can transfer. This will effect
  the LS command so that LS will only display the files that can
  be processed by FTP. The DIR command will continue to work as
  normal in that, all items such as GDG's VSAM files, and ATL will
  be displayed.
  FTP has been changed to sort the GDS file names before returning
  them to the client.

  Note: If the local current working directory is an HFS
        directory, the results are stored in a file named
        LSOUTPUT.
        LS will only list files that FTP can process. Items such
        as GDG base, VSAM files, ATL library will not be
        displayed. See the FTP DIR command to list all types.
