SAS Studio currently (Viya 2024.08) uses the same icon for SAS Program nodes in flows regardless whether it is embedded code or referenced external file.
Looking at a flow, there is no way to distinguish between those two types. If you want to know, you need to click on every single node and look to Code or Node tabs.
It would be very beneficial SAS Studio can use different icons for SAS Program nodes based on whether it is embedded code or referenced external file.
The same holds for Python Program node.
I believe it takes just a little effort with the great impact on usability.
Here are just two examples:
1. Embedded code (as there is no path shown at the top of Code tab)
2. Code referenced externally (the path to the external file is shown at the top of Code tab)
