Details
Function and attribute
names should be in
lowercase characters.
Parameters can use a
combination of lowercase
and uppercase characters.
Attribute constants use
uppercase characters
Functions can be sent with
or without white spaces.
You can specify the function
parameters by placing them
between the parentheses.
Note that the parentheses
are required even when
there are no parameters
specified.
Some commands require
multiple parameters, which
must be separated by

Place a colon (:) between
two values to specify a

Examples
An example of the scriptVar.save()
function (where test8 is the name of the
script):
test8.save()
In the command below, which sets the format
of data transmitted from the instrument to
double-precision floating point,
format.REAL64 is the attribute constant and
format.data is the attribute command:
format.data = format.REAL64
The following functions, which set digital I/O
line 3 low, are equivalent:
digio.writebit(3,0)
digio.writebit (3, 0)
The following function specifies all overlapped
commands in the nodes in group G must
complete before commands from other groups
can execute:
waitcomplete(G)
The command below reads the value of the
local time zone (no parameters are needed):
timezone = localnode.gettimezone()
This command sets the beeper to emit a
double-beep at 2400 Hz, with a beep sequence
of 0.5 seconds on, 0.25 seconds off, and then
0.5 seconds on:
beeper.beep(0.5, 2400)
delay(0.250)
beeper.beep(0.5, 2400)
The command below replaces the active scan
