Just out of curiosity, did you verify that all three files were completely *read*, as opposed to all three opened, but only the first line of the first file being read?
/M
Actually, no I didn't verify that, in this example. I was thinking about my other program in which I used mapM over the characters of the file onto a Rand monad. That one definitely read all the characters of the file---certain processing routines were called about 30,000 times (according to the profiler). This makes sense to me now, because I was asking for the state out the other side of the mapM. Thanks, Mike
