Quick question about variables

[keithmj]

Is there a way to create a global variable that is seen system wide, like a regular programming language?

Let's say I create a variable in a study: input length = 200;

Then I want to create a scan, and maybe a custom column in my watchlist using this study. In both those cases I'd have to paste the code from the study into the scan and the custom column and change "input length = 200;" to "def length = 200;"

So, is there a way to use a type of global variable for "length" so that if I change it in the study, I don't have to manually go change it in the scan and column also? All 3 instances would use the same value set in the study.

The ToS platform does not support global variables.
You can reference your study in the scan hacker.

But the scan hacker only retrieves the study script once.
If after creating your scan, you change the variable in your study, the scan will not update.

I figured the answer was "no". However, that link is helpful. Thanks for that!
