With mallocArray. Block I/O is difficult, though. >> You might want to write a function that copies the file >> _once_ and then just call that function several times. > If I load it into memory, yes.

Looking at your program: > main = disp 100 > disp 0 = return () > disp n = > let copy x = do > eof <- isEOF > if eof > then return () > else do > line <- getLine > putStrLn line > (copy 0) > in do > copy 0 > hSeek stdin AbsoluteSeek 0 > disp (n-1) Just let the function _begin_ with the seek, copy the file, and return. Then call it 100 times. No recursion. Peter _______________________________________________ Haskell-Cafe mailing list [EMAIL PROTECTED] http://www.haskell.org/mailman/listinfo/haskell-cafe
