        !             3: .ti 0
        !             4: NAME           rf  --  RF11-RS11 fixed-head disk file

        !             7: DESCRIPTION    This file refers to the
        !             8: concatenation of both RS-11 disks.
        !             9: It may be either read or written, although writing is inherently
        !            10: very dangerous, since
        !            11: a file system resides there.
        !            12: 
        !            13: The disk contains 2048 256-word blocks,
        !            14: numbered 0 to 2047.
        !            15: Like the other block-structured devices (TC, RK)
        !            16: this file is addressed in blocks, not bytes.
        !            17: This has two consequences:
        !            18: seek____ calls refer to block numbers, not byte numbers;
        !            19: and sequential reading or writing always advance the read
        !            20: or write pointer by at least one block.
        !            21: Thus successive reads of 10 characters from this file
        !            22: actually read the first 10 characters from successive
        !            23: blocks.
        !            24: .sp

        !            32: BUGS           The fact that this device
        !            33: is addressed in terms of blocks, not bytes, is extremely
        !            34: unfortunate.  It is due entirely to the fact that
        !            35: read and write pointers (and consequently the arguments
        !            36: to seek____) are single-precision
        !            37: numbers.
