The
82160A
interface
module
for the
calculator
controls
the
interface
loop
according to the modules operating mode - either Auto or Manual
(see MANIO).
The
Auto
mode
is the easier mode
to use
with all HP-IL
devices
including the
3468A.
This is especially true if you have one printer and/or one mass
storage
device in the loop.
In the Auto mode,
when you execute a printer or mass storage operation, the in-
terface automatically searches through the loop for the proper device to carry out
the instruction.
Hence the name AUTOIO.
For example,
if you execute the PRA
(PRint Alpha register) function when the 3468A is selected, the printer in the loop
automatically performs the operation. In the Manual mode, the printer would have
to be "SELECTED"
before the PRA function is executed.
Writing Programs
Earlier in this chapter we looked at a simple ac voltage measurement
problem and
developed
a simple -hp- Model 41C/41CV
program. That program
illustrates the
essentials of programming:
1, a Label; 2, setting up the 3468A
for a particular
measurement(s);
3, triggering
the multimeter;
and
4, inputting
the
results.
Of
course, the program must also have an END statement. For more specific informa-
tion on programming,
refer to the Owner's
Handbook
and Programming
Guide for
the -hp- Model 41C/41CV.
Let's look at the sample problem again:

83 OUTA

Line 01
is a title or "LABEL"
for the program.
Labels are used to identify a pro-
gram or subroutine.
To run the program execute the "Label",
