■ <compound command program header>
<compound command program header> is a command program header that ex-
ecutes a compound function. <program mnemonic> is always preceded by a co-
lon (:) to separate it from <compound command program header>. When only
one <compound command program header> is used, the succeeding colon (:) may
be omitted.
The MS9710C does not support this compound command program header. How-
ever, it is explained here taking into account future extension.
● Function On a complex device, a device command set is organized logically by providing a
compound function instead of limiting the number of unique headers. A hierar-
chical command structure can be handled effectively.
● <Example 1> To allow the MS9710C to use all device commands of another model (e.g., model
MSXXXX), the compound program header would be
:MSXXXX
● <Example 2> To allow the MS9710C to use a WXYZ device command of another model (e.g.,
model MSXXXX), the compound program header would be
MSXXXX:WXYZ or :MSXXXX:WXYZ
● <Example 3> The name of a white buck rabbit living in a FOREST is WHITE.
The name of a white doe rabbit living in a GROVE is WHITE, too. If only
WHITE is used as a command, we cannot distinguish between the above rabbits.
FOREST:WHITE or :FOREST:WHITE ......... White buck rabbit
GROVE:WHITE or :GROVE:WHITE............. White doe rabbit
■ <common command program header>
An asterisk (
∗) is always added before <program mnemonic> of <common com-
mand program header>. “Common” means that this command is a program com-
mand which commonly used for other IEEE 488.2-ready measuring instruments
connected to the bus.
● <Example> To idle completion of operation of the device at address 8, which is connected to
the GPIB interface corresponding to select code 1, and restore devices to their
initial states, the following common command is used:
WRITE @108:"∗RST" ...... The character string enclosed with quotation marks
(" ") is an IEEE 488.2 common command ∗RST for
executing the above processing.
