Try to edit batch files with CHOICE, but can't experiment under XP, always prompts: 'CHOICE' is not an internal or external command, nor is it a runnable program or batch file.

What should I do????

It seems that XP is not installed with choice by default:P

How can I install it?

C:\TEMP>choice.exe /?



CHOICE     



描述:

    该工具允许用户从选择列表选择一个项目并返回所选项目的索引。



参数列表:

   /C    choices       指定要创建的选项列表。默认列表是 "YN"。



   /N                  在提示符中隐藏选项列表。提示前面的消息得到显示，

                       选项依旧处于启用状态。



   /CS                 允许选择分大小写的选项。在默认情况下，这个工具

                       是不分大小写的。



   /T    timeout       做出默认选择之前，暂停的秒数。可接受的值是从 0

                       到 9999。如果指定了 0，就不会有暂停，默认选项

                       会得到选择。



   /D    choice        在 nnnn 秒之后指定默认选项。字符必须在用 /C 选

                       项指定的一组选择中; 同时，必须用 /T 指定 nnnn。



   /M    text          指定提示之前要显示的消息。如果没有指定，工具只

                       显示提示。



   /?                  显示帮助消息。



   注意:

   ERRORLEVEL 环境变量被设置为从选择集选择的键索引。列出的第一个选

   择返回 1，第二个选择返回 2，等等。如果用户按的键不是有效的选择，

   该工具会发出警告响声。如果该工具检测到错误状态，它会返回 255 的

   ERRORLEVEL 值。如果用户按 Ctrl+Break 或 Ctrl+C 键，该工具会返回 0

   的 ERRORLEVEL 值。在一个批程序中使用 ERRORLEVEL 参数时，将参数降

   序排列。



示例:

   CHOICE /?

   CHOICE /C YNC /M "确认请按 Y，否请按 N，或者取消请按 C。"

   CHOICE /T 10 /C ync /CS /D y

   CHOICE /C ab /M "选项 1 请选择 a，选项 2 请选择 b。"

   CHOICE /C ab /N /M "选项 1 请选择 a，选项 2 请选择 b。"

I've pressed a choice.exe for Windows Server 2003 for you. Copy it to your XP and see if it can be used :)

C:\TEMP>choice.exe /?



CHOICE     



Description:

    This tool allows the user to select an item from a choice list and returns the index of the selected item.



Parameter List:

   /C    choices       Specifies the list of options to create. The default list is "YN".



   /N                  Hides the option list in the prompt. The message preceding the prompt is displayed, and the options remain enabled.



   /CS                 Allows case-sensitive options to be selected. By default, this tool is case-insensitive.



   /T    timeout       The number of seconds to pause before making the default selection. Acceptable values are from 0 to 9999. If 0 is specified, there will be no pause and the default option will be selected.



   /D    choice        Specifies the default option after nnnn seconds. The character must be in the set of choices specified with /C; also, /T must be used to specify nnnn.



   /M    text          Specifies the message to display before the prompt. If not specified, the tool only displays the prompt.



   /?                  Displays help message.



   Note:

   The ERRORLEVEL environment variable is set to the key index selected from the choice set. The first choice listed returns 1, the second returns 2, and so on. If the key pressed is not a valid choice, the tool beeps. If the 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 using the ERRORLEVEL parameter in a batch program, order the parameters in descending order.



Examples:

   CHOICE /?

   CHOICE /C YNC /M "Press Y to confirm, N to reject, or C to cancel."

   CHOICE /T 10 /C ync /CS /D y

   CHOICE /C ab /M "Select a for option 1, b for option 2."

   CHOICE /C ab /N /M "Select a for option 1, b for option 2."

　　The choice command is not built-in in XP by default, right?

　　I'll also download it and give it a try～

Vista also supports choice, it seems that Microsoft really has a hard time making a choice

But in XP, there is set /p available for use

@echo off

set /p a=请输入你要赋给变量a的值:

echo %a%

pause

@echo off

set /p a=Please enter the value you want to assign to variable a:

echo %a%

pause

Got it~～～～～～～:D

You can copy the choice command under Win2003 to XP.

I also encountered such a problem:
Try to use CHOICE to edit a batch file, but it cannot be experimented under XP. It always prompts: 'CHOICE' is not an internal or external command, nor is it a runnable program or batch file.
