-------------------- REDIRECTION - A Special DOS Feature --------------------
REDIRECTION allows a program to direct its output to a target other than the
display screen or to receive its input from a source other than the keyboard.
FORMAT: <[d:][path]filename[.ext] for input from a file
>[d:][path]filename[.ext] for output to a file
>PRN for output to a printer
>>[d:][path]filename[.ext] for appended output to a file
REMARKS:
If a program obtaining its input from a file via redirection ("<") tries to
read data after end-of-file, DOS will be unable to supply the data and
processing will stop. In this event, use Control-Break to return to DOS.
Redirection will not work if the program involved in redirection does not use
DOS function calls to perform standard input and output.
EXAMPLES:
Redirect the output of the DIR command to the printer:
DIR > PRN
Sort a directory display and write it to the file DIRFILE:
DIR | SORT > DIRFILE
Append the output of the TREE command to the file TREEHIST:
TREE >> TREEHIST
