[Batch File] CHOICE Parameter

CHOICE is available again in Windows Vista and later versions.

Syntax:

CHOICE [ /C choices ] [ /N ] [ /CS ] [ /T timeout /D choice ] [ /M text ]
Description:
	This tool allows users to select one item from a list of choices and returns the index of the selected choice.
Parameter List:
	/C choices		Specifies the list of choices to be created. Default list for English versions is YN
	/N		Hides the list of choices in the prompt. The message before the prompt is displayed and the choices are still enabled.
	/CS		Enables case-sensitive choices to be selected. By default, the utility is case-insensitive. Note: DOS and NT Resource Kit versions use /S instead
	/T timeout		The number of seconds to pause before a default choice is made. Acceptable values are from 0 to 9999. If 0 is specified, there will be no pause and the default choice is selected. Note: DOS and NT Resource Kit versions use /T:default,timeout instead.
	/D default		Specifies the default choice after timeout seconds. Character must be in the set of choices specified by /Coption and must also specify timeout with /T. Note: DOS and NT Resource Kit versions use /T:default,timeout instead.
	/M text		Specifies the message to be displayed before the prompt. If not specified, the utility displays only a prompt.
	The ERRORLEVEL is set to the offset of the index of the key that was selected from the set of choices. The first choice listed returns a value of 1, the second a value of 2, and so on. If the user presses a key that is not a valid choice, the tool sounds a warning beep. If tool detects an error condition, it returns an ERRORLEVEL value of 255. If the user presses CTRL+BREAK or CTRL+C, the tool returns an ERRORLEVEL value of 0. When you use ERRORLEVEL parameters in a batch program, list them in decreasing order.

Examples:

• The command:
  
  CHOICE /M "Do yo really want to quit"
  
  Will display the following line:
  
  Do yo really want to quit? [YN]
  
  If the user presses Y, CHOICE exits with return code ("errorlevel") 1 (1st character in choices), if the user presse N, CHOICE exits with return code 2 (2nd character in choices).
   
• CHOICE /C ABCDN /N /T 10 /D C /M "Format drive A:, B:, C:, D: or None?"
IF ERRORLEVEL 1 SET DRIVE=drive A:
IF ERRORLEVEL 2 SET DRIVE=drive B:
IF ERRORLEVEL 3 SET DRIVE=drive C:
IF ERRORLEVEL 4 SET DRIVE=drive D:
IF ERRORLEVEL 5 SET DRIVE=None
ECHO You chose to format %DRIVE%
  
  The CHOICE command in this example will prompt the user with the following line:
  
  Format drive A:, B:, C:, D: or None?
  
  If the user presses C, CHOICE exits with a return code ("errorlevel") 3 (3rd character in choices).
  The IF ERRORLEVEL checks for 1, 2 and 3 are true (see the errorlevel page for an explanation of errorlevels), so the variable DRIVE will be set to "drive A:" first, then to "drive B:", and finaly to "drive C:".
  So the ECHO command will display the line:
  
  You chose to format drive C:
