The command was first introduced as an external command with MS-DOS 6.0. It is included in Novell DOS 7 and IBM PC DOS 7.0, and is also available from the command-line shell of some versions of Microsoft Windows, but not under Windows 2000 and Windows XP. It was first made available for Windows in the Windows XP Resource Kit. It has been reintroduced in Windows Server 2003 and is present in later versions. Starting with Windows 2000, the SET command has similar functionality using the /P command-line argument. However this command requires an additional key stroke, which is not required by choice. The choice command has been ported to OS/2, Rexx and Perl. It is also available in FreeDOS, PTS-DOS, and ReactOS. The FreeDOS version was developed by Jim Hall and is licensed under the GPL v2.
Usage
The command returns the selected choice as an exit code which is set to the index of the key that the user selects from the list of choices. The first choice in the list returns a value of 1, the second a value of 2, and so forth. If a key is pressed that is not a valid choice, the command will sound a warning beep. If an error condition is detected, an exit code value of 255 will be returned. An exit code value of 0 will be returned if the user presses + or +. Choice displays the default choices Y and N if used without parameters.
/Cchoices Specifies allowable keys. The default is "YN".
/Tnn This defaults choice to /D after "nn" seconds. Must be specified with default /D.
/Dc This defaults choice to 'c'.
/M text Specifies the prompt string to display.
Flags:
/N Specifies not to display the choices and "?" at end of prompt string.
/CS Specifies that choice keys should be treated as case sensitive.
Example
The batch file below gives the user three choices. The user is directed depending upon his input by evaluating the exit code using the IF ERRORLEVEL command. The selected choice is then printed to the screen using the ECHO command. @ECHO off @CHOICE /C:123 IF ERRORLEVEL 3 GOTO three IF ERRORLEVEL 2 GOTO two IF ERRORLEVEL 1 GOTO one GOTO end ECHO You have pressed "1"! GOTO end ECHO You have pressed "2"! GOTO end ECHO You have pressed "3"! @PAUSE
