function fn(a, b) {
return a + " " + b;

var result = fn("hello", "world");

RoboTaskApp.AddUserVariable(RoboTaskApp.ExpandText(VariableNameResult, result);

could help format the synthase

The script is

  }

VariableNameResult = "ResVar";
result = myfn("hello", "world");

RoboTaskApp().SetUserVariable(VariableNameResult, result);

I'd like to return to this post so I don't have to open another one, in this variable assignment context
in this context the variable is always applying globally, I'd like it to be only within the task
I've already declared it at the beginning of the task with the same name as the variable assigned in the function, the function applies globally, this interferes with another task with the same variable name

Try to use variable name like this: "local@ResVar"
Also you can create local variable with necessary name

Look at my example below. I have global variable MyVar. By the script set value to local variable MyVar

Also read about prefixes here: https://robotask.com/help/index.html?pr ... iables.htm

[pyhton]

from robotask import *
a = 23.5
b = 37.8
c = a + b
rt = RoboTask()
rt.set_user_var('local@MyVariable', str(c))

if it is correct, it is not working, it is not applying the variable

Unfortunately Python Script and Node.JS script actions can set only local variables now and does not process prefixes.
We'll fix this problem in next release.
