The system environment variables, that should not be confused with VC environment variables presented in the section on the environment node element, can be accessed through VC. The access path for these variables is {$ENV:<variable_name>} in which <variable_name> represents the ID of an environment variable such as PATH or PWD.
The example below outputs the path environment variable.
<action>
<write_console value="Path: ({$ENV:PATH})" />
</action>
