How is : this so? : 1: NO it's not a true pipe and it's NOT multitasking. 2: it creates a temporary file and spools it up tell the first program is finished then it redirects stdin for the next program to the temp file and runs that program. AND so one. Until it completes the task. It's an illusion. -- This is my sig file! Read rec.games.programer!
