Difference Variable: Load-Editor vs. App

george55 — Fri, 20 Dec 2019 13:46:12 GMT

Hi all,

What is the difference between creating a variable in Load Editor (set / let) and in the App itself (see picture below)?

Are there any disadvantages/advantages using one or the other?

One advanced in the Load Editor I see, but please correct me if I am wrong, is to generate a 'order'. Hence able to control the dependencies of the variables.

Thanks for any help.

George

Hi George,

The advantages to creating them in the load editor:

You can store your variables in a text file, and then use an Include to bring them into the load editor. This is the preferred method for global variables across multiple apps.
You can, as you said, choose Let vs. Set.
It's quicker to update many variables in the load editor.

The only advantage I can think of to creating a variable in the App:

You don't have to wait for the reload

Note that a variable created in the load editor, and then removed from the load editor after a load, will remain in the variables list in the app.

Thanks Laurischarf

So I will use going forward variable only in the load editor. advantages outweigh the disadvantages.

And as I said, a further advantage in load editor, is to be able to put the variables in an order:
let x = 1+3
let y = x +1
