  * GIMUNZIP creates output data sets with                       *
  * incorrect space allocation.                                  *

  * RECOMMENDATION:                                              *
  ****************************************************************
  GIMZIP calculates a data set's allocated space in number of
  Records with a length of the data set's block size.  It does
  this in an attempt to identify space in device independent
  units, just in case the track size differs on different device
  types.  GIMZIP does this regardless of the space unit in which
  the original data set was allocated.
  GIMUNZIP therefore allocates new output data sets with space in
  Records, as identified by GIMZIP.  Unfortunately when allocating
   a data set with space in Records, the system may calculate the
  actual number of tracks on the volume for the data set to be
  significantly larger than the original zipped data set.  This
  means the resulting output data set is larger than expected,
  potentially leading to volume out of space conditions when many
  data sets are unzipped onto a single volume.
  

Problem conclusion

• GIMUNZIP has been modified in SMP/E V3.7 to create new output
  data sets with space allocated in Tracks instead of Records.
  GIMUNZIP converts a data set's identified space in number of
  Records to Tracks, by assuming the output data set's device has
  3390 DASD device geometry, 56,664 bytes per track.
