(Alpha and Integrity servers) MAXBOBMEM defines the maximum
    amount of physical memory, measured in pagelets, that can be
    associated with a single buffer object created by a process
    in user mode. The default value of 0 means there is no system-
    imposed limit on the size of a buffer object.

    MAXBOBMEM is a DYNAMIC parameter.

    Other MAXBOB* parameters are obsolete beginning with OpenVMS
    Version 7.3.
