Figure 1-32. Simplified Response Message Syntax
Resp onse messages can con tain b oth commas and semicolons as
separators. When a single query command returns m ultiple v alues,
a comma separates eac h data item. When m ultiple queries are sen t
in the same message, the groups of data items corresp onding to eac h
query are separated b y a semicolon. F or example, the ctitious query
:QUERY1?:QUERY2? might return a resp onse message of:
<data1>,<data1>;<data2>,<data2>
Resp onse data t yp es are explained later in this subsection. Note that
<new line><^END> is alwa ys sen t as a resp onse message terminator.
