TOPs environment variables __PDG_DIR__ instead of ${PDG_DIR}

[art3mis]

Noob question

In the sesi documentation it suggests to use __PDG_DIR__ instead of ${PDG_DIR} for filename paths.

ok, I tried and only received errors in the graph when cooking ROP Geo Output.

That's the first issue

2nd is a noob question on proper use of envirnment variables in TOPs

What is the difference between

${PDG_DIR}

$PDG_DIR/

and

__PDG_DIR__   ?

 

I'm on Linux (Ubuntu 18.04LTS)
