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.
