for the specified dataset.

| **dsarch** [:ref:`-(DS|Dataset) <DS>`] dNNNNNN [-](DG|DeleteGroup) [:ref:`Mode Options <mode3.3.3>`]
|            :ref:`-(GI|GroupIndex) <GI>` GroupIndices
|           [:ref:`-(LN|LoginName) <LN>` LoginAccountName]

   * - :ref:`-(MD|MyDataset) <MD>`
     - allows any specialist to set GDEXDB information, regardless of dataset ownership
   * - :ref:`-(NT|NoTrim) <NT>`
     - skips trimming of spaces and comments from input values, speeding up input file processing
   * - :ref:`-(RT|ResetTGroup) <RT>`
     - resets the top group index for file records in the affected group
   * - :ref:`-(WN|WithFileNumber) <WN>`
     - re-evaluates and resets file counts for the affected groups

Specify groups by index via :ref:`-GI <GI>` and the dataset via :ref:`-DS <DS>`. Deletion is
blocked if a group still contains subgroups or data files. To delete
a non-empty group, first retrieve its files with :ref:`-GS <GS>` (-GetSavedFile)
or :ref:`-GW <GW>` (-GetWebFile), then either move them to another group via :ref:`-CG <CG>`
(-ChangeGroup), reset their group index to 0, or remove them with
:ref:`-DL <DL>` (-Delete). Once empty, the group can be deleted.
