The MAPS command examines or updates bitmaps. The format of the MAPS command is:

         M[APS] -BL[OCK]=block-number
                -BU[SY]
                -F[REE]
                -M[ASTER]
                -R[ESTORE_ALL]
        

MAPS can flag blocks as being either -BUSY or -FREE. The -MASTER qualifier reflects the current status of a local bitmap back into the master map. The -RESTORE_ALL qualifier rebuilds all maps and should be used with caution since it can destroy important information.

By default, MAPS shows the status of the bitmap for the specified block.
