The status field of a tape is coded as a bitmask using one bit per
attribute.  Current known bit positions in this mask are:

Bit 0   (mask of decimal 1, hex 0x001)  Frozen
Bit 1   (mask of decimal 2, hex 0x002)  Suspended
Bit 2                                                   ???
Bit 3 (mask of decimal 8, hex 0x008)    Tape Full

Bit 4                                                   ???
Bit 5                                                   ???
Bit 6 (mask of decimal 64, hex 0x040)   Multiple retentions mixed onto
single tape
Bit 7 (mask of decimal 128, hex 0x080)  Volume contents imported

Bit 8                                                   ???
Bit 9 (mask of decimal 512, hex 0x200)  Multiplexed images

Note that to encode a full, frozen tape, you simply "or" the corresponding
bits (if you prefer, you can "add" the decimal masks) to arrive at 1+8 => 9.
