Figure l-31. Simplified Common Command Syntax
As with subsystem commands, use a <space> to separate a
command mnemonic from subsequent parameters. Separate adjacent
parameters with a comma. Parameter types are explained later in
this subsection.

Figure l-32. Simplified Response Message Syntax
Response messages can contain both commas and semicolons as
separators. When a single query command returns multiple values,
a comma separates each data item. When multiple queries are sent
in the same message, the groups of data items corresponding to each
query are separated by a semicolon. For example, the fictitious query
:
QUERYl?
:
qUERY2?
might return a response message of:
<datal>,Cdatal>;<data2>,Cdata2>
Response data types are explained later in this subsection. Note that
<new line><-END> is always sent as a response message terminator.
