The Syntax of Program Messages
This section details the format and parameters of program messages.
Program messages are sent by the computer to the measuring device. They are
comprise one or more commands, the symbols that separate each command, and a
message termination symbol (terminator).
Uppercase and Lowercase Letters
No distinction is made between uppercase and lowercase letters in program
messages.
Program Message Terminator
The program message terminators are
<newline>
,
<^END>
, and
<newline><^END>
.
<^END>
is used to indicate the end of a program message.
<^END>
means that an EOI (End Of Identify) was transmitted, signaling that data
transmission through an GPIB interface has been completed.
For example, the
HP BASIC OUTPUT
statement automatically adds an
<^END>
to the end of data transmissions. For IBM PC computers, the specification for the
terminator that is transmitted can be changed by changing the environment
settings of the system.
Multi-messages
More than one command can be included in a message. When this is done a
semicolon is used to separate the commands.
