The output DFSMSrmm returns when you specify the SEARCHDATASET subcommand and the EDGXCI macro OUTPUT=FIELDS and EXPAND=NO parameters is:

<Begin DATASET Group>
  <DSN  - Data Set Name            : 44, character         >
  <VOL  - Volume Serial            :  6, character         >
  <OWN  - Owner                    :  8, character         >
  <TZ   - Time Zone                :  4, bin(32)           >
  <CDTJ - Create Date              :  4, packed decimal    >
  <CTM  - Create Time              :  4, packed decimal    >
  <FILE - Physical File Sequence   :  4, bin(32)           >
  <RTDJ - Retention Date           :  4, packed decimal    >
  <XDTJ - Expiration Date          :  4, packed decimal    >
<End DATASET Group>

The expanded output that DFSMSrmm returns when you specify the SEARCHDATASET subcommand with the OUTPUT=FIELDS and EXPAND=YES parameters is the same as shown in LISTDATASET structured field introducers for LISTDATASET.
