LOCATE Command (2Bh)
The LOCATE command is used to do high-speed positioning to the specified block
address.
The READ POSITION command can be used to obtain the block address, when writing,
when particular blocks of data (a data file, for example) are about to be written. The
LOCATE command can then be used to position the tape back at the same logical
position for high performance restore operations of particular blocks of data.
