returns the response message
0;0,"No errors"
If the command that follows the semicolon has a different header path from the
root level, you must use a colon to force a return to the root level:
SYSTem:VERSion?;:TEST:RESult?
If the command that follows the semicolon has the same header path, you may
omit the colon and the path and state only the new leaf node. This makes it
possible, for example, to shorten the concatenated query
SYSTem:TIME:LMAintenance?;:SYSTem:TIME:ON?
into
SYSTem:TIME:LMAintenance?;ON?
The 488.2 common commands that begin with an asterisk (*) may be used
anywhere in a command sequence with no effect on the command header path.
SYSTem:VERSion?;*ESR?
returns
1995.0;16
You can combine commands and queries into the same message. Note, for
example, the following combination which sets the temperature limit and queries
to verify the setting
status:questionable:temperature:limit AMBient,25;limit?
