Introduction to Programming
Program Message Terminator
Program Message Terminator
The program instructions within a data message are executed after the
program message terminator is received. The terminator may be either an NL
(New Line) character, an EOI (End-Or-Identify) asserted in the HP-IB
interface, or a combination of the two. Asserting the EOI sets the EOI control
line low on the last byte of the data message. The NL character is an ASCII
linefeed (decimal 10).
New Line Terminator Functions
The NL (New Line) terminator has the same function as an EOS (End Of String)
and EOT (End Of Text) terminator.
Selecting Multiple Subsystems
You can send multiple program commands and program queries for different
subsystems on the same line by separating each command with a semicolon.
The colon following the semicolon enables you to enter a new subsystem. For
example:
<program mnemonic><data>;:<program mnemonic><data><terminator>
:CHANNEL1:RANGE 0.4;:TIMEBASE:RANGE 1
Combining Compound and Simple Commands
Multiple commands may be any combination of compound and simple
commands.
