.2.4 Headers
(1) Program message headers
The program message always requires a header.
These are three types of header: simple headers, compound headers, and
particular headers.
Simple header
A header consisting of a single word beginning with a letter.
Example :AUTorange
Compound header
A header consisting of a sequence of words separated by colons.
Example LOCK:KEY
Particular header
A header beginning with an asterisk (
*
) to indicate that it is a particular
command.
Example *CLS
(2) response message
Headers in response message can be enabled or disabled by using the
"HEADer" command.
Example "CSET:BEEP?" (Queries the buzzer setting)
Response: [If headers are ON] :CSET:BEEPERIN
Response: [If headers are OFF] IN (Data only)
