	When MORE knows the file it's working with, it can tell its size
	and calculate the percent left.  However, if it's just reading
	standard input (e.g.- from a pipe as you describe), if has no idea
	where the file ends so it can't estimate percent complete.  At least
	it's smart enough not to try.

	What happens here is interesting:

   -	First, DOS runs TYPE with no arguments.  The result is the error
	message, since TYPE _must_ have a filename argument.

   -	Next, DOS runs MORE with the filename argument and _also_ STDIN.
	(Of course, STDIN is null, because TYPE failed.)  The messages
	you get here are from MORE running _with_ a filename argument,
	so it can tell the size of the file.

Hope this helps.
