/sys$common/syshlp/helplib.hlb System Services, $DELTVA 64 (Alpha Only)  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    On Alpha systems, deletes a range of virtual addresses from a
    process's virtual address space. Upon successful completion of
    the service, the deleted pages are inaccessible, and references
    to them cause access violations.

    This service accepts 64-bit addresses.
