(4) Example of command use.
(5) This lists the functions in which the command may be used.
Execution of commands

> *Commands are input into the input buffer and are executed in order.
> *However the :ABORT command is executed immediately, even if commands
> are waiting in the input buffer - more precisely, at the instant its
> terminator is received.
> *Commands other than those which can be handled by the unit in its
> current state are not executed but generate execution errors.
> This happens, for example, when in memory recorder function it is
> attempted to execute a recorder mode setting.
> *Further, The commands other than the following cannot be executed
> during measurement operation.
> :STOP, :ABORT, *OPC, *WAI, :HEADer
> *The query command is executed during measurement , other than those
> which can be handled by the unit in its current state.

         Syntax        (command)     *OPC
         Explanation   When the command preceding the *OPC command completes
                       execution, the LSB of SESR is set.
         Example       A$;B$;*OPC;C$
                       (After the execution of the commands A$ and B$ is
                       completed, the LSB of SESR is set.)

         Note          Please do not use it for the watch of the start processing when the record time continuousness is turning on.

-4.Status and event control commands

    (1) *CLS  --- Clears the status byte and associated queues
                  (except for the output queue).
         Syntax        (command)    *CLS
         Explanation   This instruction clears the event register associated
                       with each bit of the status byte register.
                       It also clears the status byte register.
         Note          Because it does not clear the output queue, it has no
                       effect upon bit 4 (MAV) of the status byte.

    (2) *ESR?  --- Reads out and clears the contents of the standard event status

                       value.

    (3) *STB?  --- Reads the status byte and MSS bit.
         Syntax        (query)       *STB?
                       (response)    A <NR1>
                                     A = 0 to 255
         Explanation   This is the same as reading out the status byte.
         Note          Bit 6 is not RQS, but is MSS.

    (4) :ESR0?  --- Reads and clear event status register 0 (ESR0).
         Syntax        (query)      :ESR0?
                       (response)   A <NR1>
                                    A = 0 to 255
         Explanation   The contents of ESR0 are returned as an NR1 numerical

                                     A = error no.
         Explanation   The number of error or warning that has occurred on the
                       unit is returned in <NR1> as a numerical value.
                       (For errors or warnings, refer to the instruction manual
                       included with the unit.)
