VMS Help RTL Routines, LIB$, LIB$FREE_VM_PAGE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The Free Virtual Memory Page routine deallocates a block of
    contiguous pages on VAX systems or pagelets on Alpha systems
    that were allocated by previous calls to LIB$GET_VM_PAGE.
