-BL[OCK]=block_number

Specifies the target block for MAPS. The -BLOCK qualifier is incompatible with the -RESTORE_ALL qualifier.

On commands with no -BLOCK= or -RESTORE_ALL qualifier, DSE uses the last block handled by a DSE operation. When no block has been accessed, that is, on the first block-oriented command, DSE uses block one (1).

-BU[SY]

Marks the current block busy in the block's local map and appropriately updates the master bitmap. The -BUSY qualifier is incompatible with all qualifiers except -BLOCK.

-F[REE]

Marks the current block free in the block's local map and appropriately updates the master bitmap. The -FREE qualifier is incompatible with all qualifiers except -BLOCK.

-M[ASTER]

Sets the bit in the master bitmap associated with the current block's local map according to whether or not that local map is full. The -MASTER qualifier is incompatible with all qualifiers except -BLOCK.

-R[ESTORE_ALL]

Sets all local bitmaps and the master bitmap to reflect the blocks used in the database file. Use -RESTORE_ALL only if the database contents are known to be correct, but a large number of the bitmaps require correction. The -RESTORE_ALL qualifier is incompatible with all other qualifiers.
