| 6 | * TP_BSIZE is the size of file blocks on the dump tapes. | |

| 9 | * NTREC is the number of TP_BSIZE blocks that are written | |

| 12 | * BLKING calculates the number of TP_BSIZE blocks in a file | |

| 15 | * TP_NINDIR is the number of indirect pointers in a TS_INODE | |
| 16 | * or TS_ADDR record. Note that it must be a power of two. | |
