VMS Help CMS, RESERVE, Qualifiers, /NOHISTORY  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Prevents CMS from including the element history in the file. If
    you omit /NOHISTORY, and the retrieved element has the history
    attribute, CMS includes the element history in the output file. An
    element has the history attribute if the /HISTORY qualifier was
    specified on the CREATE ELEMENT or MODIFY ELEMENT command.
