*CLS (No Query
Form)
This command (no query form) clears the following:
Event Queue
Standard Event Status Register
Status Byte Register (except the MAV bit)
If the *CLS
command immediately follows an <EOI>, the Output Queue and
MAV bit (Status Byte Register bit 4) are also cleared. MAV indicates that
information is in the output queue. The device clear (DCL) GPIB control message
will clear the output queue and thus MAV. *CLS does not clear the output queue
o r M AV.
*CLS can suppress a Service Request that is to be generated by an *OPC. This
will happen if a single sequence acquisition operation is still being processed
when the *CLS command is exec uted.

CMDBatch
This command sets or queries the state of command batching. By batching
commands, database transactions can be optimized, increasing c ommand
throughput. Also, batching allows for ALL commands in an individual batch to
be order independent and accomplish the same result as if the commands were
coupled.
The Batch state is persistent and will be saved across power cycles, but will not
be saved and recalled as part of a setup. In a setup scenario, the factory initial
value is enabled.
