    Dsname Level  ===>                                              More? ===> N
    Volume Serial ===>                    (Leave BLANK for catalog scan,
                                          volser or pattern for VTOC scan)
 Data set list options:
    Initial View  ===> 1 :  1. Volume  2. Space   3. Attrib   4. Total
    Enter "/" to select option:
    / Confirm Data Set Delete      / Additional Dataset Qualifiers
    / Display Catalog Name         / Display Total Tracks

 the available line commands. TSO commands, CLISTs, or REXX execs are supported.

There are several enhancements:

An XV (Extended VTOC & space summary) command displays detailed information about a volume, along with a space usage graphical bar. You can type over the volume serial to switch to another volume, and immediately see the graphical bar and the detailed information change.
The GDG (Display Generation Data sets) command opens a temporary OLIST listing all the existing generations of a GDG base, showing both the relative generation number and the physical data set name. You can use all the OLIST commands on these data sets, including pattern matching. See Patterns for instructions on how to apply pattern matching.
The More? prompt following the Dsname Level input field opens a pop-up window allowing you to specify multiple DSNAME levels and VOLSERs. Data Set Commander responds by opening a temporary OLIST containing the data sets that match the multiple criteria you specify. It is typically used to create a list of different catalog levels.
The Action Bar contains a new option: Special-lists. When selected, Data Set Commander presents options that let you open OLISTs containing data sets from special sources, like the allocated data sets, the migrated data sets, and other sources.
Extended VTOC Display & Space Summary

The XV command displays extended VTOC information. If you specify all volumes by entering "*" for volume serial, a Space Summary Volume Selection list is displayed:

You can use pattern matching wild cards to narrow down the initial list.
