Example 2
Code
add_three = function(parameter1,
parameter2, parameter3)
return parameter1 + parameter2 +
end
print(add_three(3, 4, 5))
Example 3
Code
function sum_diff_ratio(parameter1,
parameter2)
psum = parameter1 + parameter2
pdif = parameter1 - parameter2
prat = parameter1 / parameter2
return psum, pdif, prat
end
sum, diff, ratio = sum_diff_ratio(2, 3)
print(sum)
print(diff)
print(ratio)
Create functions using scripts
You can use scripts to define functions. Scripts that define a function are like any other script: They
do not cause any action to be performed on the instrument until they are executed. The global
variable of the function does not exist until the script that created the function is executed.
A script can consist of one or more functions. Once a script has been run, the computer can call
functions that are in the script directly.
The following steps use TSB Embedded. You can also use the loadscript and endscript
commands to create the script. See
(on page 6-5).
