There are a couple of things to say here. The lack of output has nothing to do with the environment variable. The echo command is running within the new screen session, to which you are not attaching (and which will exit after echo exits.) So nothing should appear as output in the current shell. Try: $ screen -d -m echo foo to see the same thing (nothing) in your current shell. However, since you used -L to enable logging, you should see the output in the log. Finally, note that $FOO gets expanded by the current shell before screen is invoked. If you want different behavior, please be more specific about what you are really trying to accomplish.
