Are there module-global variables in Uniface using $variable$?

Hey everyone, 👋

I've recently been working with Uniface and someone told me that module-global variables exist in Uniface. These are supposedly recognizable by a dollar sign ($) before and after the variable name, such as:
$temp$
However, when I searched for the term "module global variable" in the Uniface documentation, I couldn’t find any results. 🤔

My questions:
🔹 Are these variables really module-global, or do they have another function?
🔹 Where can they be defined and accessed?
🔹 Is there an official list of these $variables$ in the documentation?

Would love to hear from anyone with Uniface experience! 🚀

Thanks in advance! 😊

My colleague told me that if the module global variable is defined in a service A, it can only be used in service A and not in service B or service C
