If the link bit is one, a command is linked to the SEARCH DATA
EQUAL command.
If the search is successful, the next command is
executed.
The next command may use the Relative Address Bit, in
which case the logical block address is a displacement from the
block at which the search was satisfied.
If a linked search is
not satisfied, the command is terminated with a Check Condition
status.
A Request Sense can then be issued to determine the
nature of the termination.
When a search is satisfied, it will terminate with a Condition
Met Status. A Request Sense Command can then be issued to deter-
mine the block address of the matching record.
A Request Sense following a successful Search Data command will:
1)
Set the Address Valid bit to one.
2)
Report the address of the block containing the first matching
record in the Information Bytes.
The Request Sense command following an unsuccessful Search Data
command will:
1)
Report an error code of No Sense (00 H ), provided no errors
occurred.
2)
Set the Va lid bi t to zero.
Figure 6-44 shows the SEARCH DATA EQUAL argument.
