Under DOS, since only one thing ran at a time, this didn't actually 
"pipe" the data. It was just a shortcut for
   type autoexec.bat >tempfile
   more <tempfile

You had to wait for the first program to finish, and you had to have 
enough disk space, before the second would start.

Pretty much every MS OS since Win3 at least has had actual pipes, tho. I 
think the command.com under Win3 still used the tempfile stuff, but the 
OS had a "make a pipe" call in it.
