​@Rachel101886 you’re right to notice the discrepancy; it used to be  <type/scope indicator><data type><Variable name> format, but over time, to make it simpler for a broad set of users, we’ve moved towards <data type><Variable name> in our newer training material. That said, you’re welcome to use any naming convention as long as it is consistent and aligns with your organisation’s needs.

Here’s a university course that offers another example: https://upskill.automationanywhere.com/learn/video/getting-started-with-variables.

I would also love to know what naming convention other community members follow!
