Environment variables are parameters that are not defined in CloverETL, they are defined in the operating system.
You can get the values of these environment variables using the same expression that can be used for all other parameters.
To get the value of environment variable called

java.io.tmpdir), replace each dot
with an underscore character and type:

With this white space we will get
\ ' at the end.
Use single quotes to avoid escape sequences in Windows paths.
