/sys$common/syshlp/helplib.hlb ACCOUNTING, /BINARY, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The /BINARY qualifier specifies that records are output in binary
    format to the file specified by the /OUTPUT qualifier. (/OUTPUT
    is Alpha-only, however.) Use the Accounting utility to process
    this file later.

    See also the /BRIEF, /FULL, and /SUMMARY qualifiers, which
    process the selected records to produce a report.

    You cannot use the /BINARY qualifier with the /BRIEF, /FULL,
    or /SUMMARY qualifiers.
