On Alpha and Integrity servers, adds sections of memory if you
    want to specify more than one resource affinity domain (RAD) for
    a single reservation.

    EXTEND does not allow you to specify any of the /ALLOCATE, /ZERO,
    or /PAGE_TABLES flags. The existing reservation determines the
    state of these flags. The /ALLOCATE flag is set implicitly with
    EXTEND, whether or not it was set for the initial reservation.

    To add a memory section without specifying a RAD, use the /NORAD
    qualifier.

    Format

      RESERVED_MEMORY EXTEND  name

1  –  Parameter

 name

    Name of the memory reservation. You must specify a name.

    If the reservation is for a memory resident global section, the
    name of the reservation must be the same as the global section
    name.

2  –  Qualifiers

2.1    /RAD

       /RAD=n
       /NORAD

    Specifies an additional memory section if you want to specify
    more than one RAD for a single reservation.

    Use /NORAD to add a memory section without specifying a RAD.

2.2    /SIZE

       /SIZE=size of reserved memory, in MBs

    Specifies the number of megabytes to be deducted from the
    system's fluid page count for this memory-resident global section
    when the VMS$RESERVED_MEMORY.DATA data file is read during system
    initialization.
