The piping feature of DOS allows you to direct the standard output of one
program to be used by another, effectively chaining a series of programs
together as a single command.  Each program to be chained together is separated
by an OR bar "|".  For example:

DIR |FIND "8-30-84" |SORT >PRN
          - The output from the DIR command is sent to the FIND command.  Each
            line that contains the time stamp 8-30-84 is sent to the SORT
            command, and the sorted listing of files updated on that date is
            sent to the printer. See the help file REDIRECT for information
            about the ">" redirection command.

*  The output from each program is stored by DOS in a temporary file in the
   root directory of the default disk, so there should be some space on the
   disk for these files.
