PI15354: FILE MANAGER I/O EXIT DOES NOT DECOMPRESS FILES THAT ARE COMPRESSED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• User selects "Use I/O exit" on FM Edit Entry Panel. The input
  file is a compressed data set, and they use their own I/O exit
  to decompress the file. FM does not display decompressed data.
  Compressed data is displayed in the FM Editor. To correct this
  issue, File Manager needs to be modified so that the IO-EXIT is
  only called when File Manager actually starts reading the data.

  * PROBLEM DESCRIPTION: 1. File Manager is incorrectly calling  *
  *                         the IO exit when performing internal *
  *                         calls to set up the file to be       *

  ****************************************************************
  1. An IO exit with restrictive conditions on the:
      o open/close processing for QSAM files
      o read processing for QSAM/VSAM files
     may cause the IO exit to stop working due to internal File
     Manager processing.
  2. File Manager is incorrectly estimating that the expanded
     compressed records will fit into memory when browsing or
     viewing a compressed file.
  

Problem conclusion

• File Manager was modified to:
  1. Call the IO exit when required.
  2. Perfom an inplace edit when browsing or viewing data using
     an IO exit.
