a semicolon. You must always end a program message with one of
the three program message terminators shown in Figure l-29. Use
<new
or <new line>
as the program message
terminator. The word
means that EOI is asserted on the
HP-IB interface at the same time the preceding data byte is sent.
Most programming languages send these terminators automatically.
For example, if you use the HP BASIC
OUTPUT
statement,
<new
is automatically sent after your last data byte. If you are
using a PC, you can usually configure the system to send whatever
terminator you specify.

Figure l-30. Simplified Subsystem Command Syntax
As Figure l-30 shows, there must be a <space> between the
last command mnemonic and the first parameter in a subsystem
command. This is one of the few places in SCPI where <space>
is required. Note that if you send more than one parameter with
a single command, you must separate adjacent parameters with a
comma. Parameter types are explained later in this subsection.
Common Command Syntax
Figure 1-31 describes the syntax of common commands.
