@ECHO   You did not type in a file path.  You must execute this batch file from 
@ECHO   either the DOS prompt or the Run dialog on the Windows Start menu.  See 
@ECHO   directions below.
@ECHO.
@ECHO.
@ECHO   DIRECTIONS:
@ECHO.
@ECHO   1. Type or copy and paste the list you want sorted into a new file,
@ECHO      making sure each item to be sorted is on a separate line, and save
@ECHO      the file.  Quick Sort will place numbers in numerical order, too, so 
@ECHO      keep that in mind if your list contains arabic numerals.
@ECHO   2. Press the Start button, Windows Start key, or CTRL+ESC together.
@ECHO.
@ECHO.
PAUSE
CLS
@ECHO.
@ECHO   3. Select Run from the Start menu.
@ECHO   4. Type in C:\QKSORT.BAT (or whatever the path is where you stored
@ECHO      QKSORT.BAT; letter case does not matter), then type a blank space,
@ECHO      followed by the path for the file you want to sort, another blank
@ECHO      space, and finally the path for the destination file where you
@ECHO      want your results to be saved.  
@ECHO   5. At either the DOS prompt or in the Run dialog, follow the example 
@ECHO      below using the name by which you chose to save your file earlier.
@ECHO.
@ECHO.
@ECHO   EXAMPLE:  c:\qksort.bat c:\sample.txt c:\sample2.txt
@ECHO.
@ECHO.
@ECHO   Note that the destination file has a different name.  While Quick-Sort
@ECHO   will append your sorted results to the end of your source file, you are
@ECHO   wise to save them to a new file to avoid source file alteration.  You 
@ECHO   should also limit your filename to eight characters or less to 
@ECHO   accommodate DOS file naming restrictions.  
@ECHO.
@ECHO.
