1    /ALPHABETICALLY

       /ALPHABETICALLY[=n[:m]]

    Sorts the histogram alphabetically by label names. If you specify
    histogram. If you specify =n:m, only buckets n through m (after
    sorting) are retained.

2    /ASCENDING

       /ASCENDING[=n[:m]]

    Sorts the histogram in ascending order by bucket data count
    (smallest count first). If you specify =n, only the first n
    buckets (after sorting) are retained in the histogram. If you
    specify =n:m, only buckets n through m (after sorting) are
    retained.

3    /DESCENDING

       /DESCENDING[=n[:m]]

    Sorts the histogram in descending order by bucket data count
    (largest count first). If you specify =n, only the first n
    buckets (after sorting) are retained in the histogram. If you
    specify =n:m, only buckets n through m (after sorting) are
    retained.

    Note that /DESCENDING is the default sorting qualifier.

4    /NOSORT

       /NOSORT[=n[:m]]

    Specifies that the histogram not be sorted. If you specify =n,
    only the first n buckets are retained in the histogram. If you
    specify =n:m, only buckets n through m are retained.
