For example, to set up a two-second beep, you could send the command:
beepTwoSec = script.new("beeper.enable = 1 beeper.beep(2, 2400)", "beepTwoSec")
To run the new script, send the command:
beepTwoSec()
When you add beepTwoSec, the global variable and script.user.script table entries are made
to the runtime environment as shown in the following figure.
Global variables
name
beepTwoSec
script.user.scripts table
beepTwoSec
Create an unnamed script using script.new()
Unnamed scripts are not available from the front panel display of the instrument. Only the anonymous
script and named scripts are available from the front panel display.
When you create a script using script.new(), if you do not include name, the script is added to the
runtime environment as an unnamed script. The script.new() function returns the script. You can
assign it to a global variable, a local variable, or ignore the return value. A global variable is not
automatically created.
For example, if you sent the command:
hello = script.new('display.clear() display.settext("hello")')
A script is created in the runtime environment and a global variable is created that references the
script.
To run the script, send the command:
hello()
