• Default label: "Get environment"
• Member of plug-in: Built-in
• Catalogue path: Builtin/System

Inputs:
Variable name		QString	The name of the environment variable to retrieve. This should be considered case-sensitive, since some platforms treat environment variables case-sensitively and others do not.
Value if missing		QString	If the named environment variable is not found, the value used at the Value if missing input is used instead. This allows a kind of fall - back behaviour to be used.
Outputs:
Value		QString	This will hold the value of the named environment variable, or if not found then the value of the Value if missing input.
