Device Listening Syntax - HP 54501A Programming Reference Manual

Device Listening
Syntax
The
listening
syntax
of
IEEE
488.2
is
designed
to be more
forgiving
than
the talking
syntax.
This
allows greater
flexibility in writing programs,
as
well
as
allowing them to
be easier to read.
Upper/Lower Case Equivalence. Upper
and lower
case
letters are
equivalent.
The
mnemonic
RANGE
has the same semantic meaning
as
the
mnemonic range.
< white
space
>.
<
white
space
>
is
defined to be one or more characters
from the
ASCII
set
of
0
-
32 decimal, excluding 10
decimal
(NL).
<
white
space
>
is used by
several instrument
listening components of
the syntax.
It is
usually optional, and can be used to increase the readability of
a
program.
