Program Message Syntax - HP 83751A Programming Manual

Program Message Syntax

These program messages contain commands combined with appropriate
punctuation and program message terminators.
common command
NOTES:
<new line> = ASCII character decimal 10
= EOI asserted concurrent with last byte
Figure 1-6. Simplified Program Message Syntax
As Figure l-6 shows, you can send common commands and subsystem
commands in the same message. If you send more than one command in the
same message, you must separate them with a semicolon. You must always
end a program message with one of the three program message terminators
shown in Figure 1-6. Use <new line>,
as the program message terminator. The word <-END> means that EOI is
asserted on the HP-D3 interface at the same time the preceding data byte is
sent. Most progmmming languages send these terminators automatically.
For example, if you use the HP BASIC OUTPUT statement, <new line> 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.
