You don't specify what exactly you want to do, but here's a couple
examples: (We'll assume you're after the contents of a variable named
"USER")

DOS batch file:

    echo %%USER%% > logfile
         -or-
    echo %USER% > logfile

Using one or two '%' is DOS version and command interpreter dependent -
experiment -- mostly I use the single until I find a place it barfs,
then add the other...

C (Turbo to be specific - check your library reference)

    char user_var[20];     /* whatever length...? */
    user_var = getenv("USER");

Hope this helps...
