/sys$common/syshlp/helplib.hlb DECTPU, TPU$FILEIO  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    The TPU$FILEIO routine handles all DECTPU file operations.
    Your own file I/O routine can call this routine to perform some
    operations for it. However, the routine that opens the file must
    perform all operations for that file. For example, if TPU$FILEIO
    opens the file, it must also close it.
