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.
