Question

我正在尝试在vDOS（DOS模拟器）中运行批处理文件，我希望用户输入两个变量。每次运行文件时，它都不允许我输入变量。

SET /P in=Input:
SET /P out=Output:

我希望发生的事情是让我输入变量的输入。相反，它按原样执行两个命令（不允许我输入输入）。

Answer 1

Windows cmd and MS-DOS are very different things，区别之一是set命令。在MS-DOS中，集合的唯一形式是set variable=value。没有set /A，set "variable=value"和set /P。

set /P是Windows NT的cmd.exe的功能。在DOS中，您必须使用3 ^rd方软件来获取用户输入并将其存储在变量中。这是一些解决方案

SENVAR.COM
```
SENVAR INPUT Input string:
```
EDITVAR and CHOOSE
```
editvar -p "Input string: " INPUT
```

FC.COM

@echo off
:: based on batch from PC Magazine June 27, 1995 page 248
:: this version puts temps in C:\DOS dir and shortens var names
:: User input is returned in variable STR
:input
> C:\DOS\en#er.bat fc con nul /lb1 /n|date|find "    1:  "
> C:\DOS\enter.bat echo set str=
>>C:\DOS\enter.bat echo :loop
>>C:\DOS\enter.bat echo if not '%%str%%==' set str=%%str%% %%5
>>C:\DOS\enter.bat echo if '%%str%%==' set str=%%5
>>C:\DOS\enter.bat echo shift
>>C:\DOS\enter.bat echo if not '%%5==' goto loop
call en#er.bat
del C:\DOS\enter.bat
del C:\DOS\en#er.bat

ANSI.SYS

@ECHO OFF

REM * Ask for USeR INPUT and store it in variable USRINPUT
REM * Assumes ANSI.SYS is loaded
REM * Written by Rob van der Woude

SET USRINPUT=

REM * Turn on ANSI key translation (translate Enter
REM * key to F6+Enter sequence) and ask for input:
ECHO ←[13;0;64;13pEnter one word only . . .

REM * Copy entered text to temporary file:
COPY CON %TEMP%.\~USRINP.TMP

REM * Turn off ANSI key translation and clear irrelevant screen output:
ECHO ←[13;13p←[3A←[K←[1B←[K←[1B←[K←[2A

REM * Add empty line to temporary file. The empty line
REM * will be used to stop DATE asking for new date.
ECHO.>> %TEMP%.\~USRINP.TMP
ECHO.>> %TEMP%.\~USRINP.TMP


REM * Create a temporary batch file that will store the
REM * entered text into the environment variable USRINPUT:
TYPE %TEMP%.\~USRINP.TMP | DATE | FIND "):" > %TEMP%.\~USRINP.BAT

REM * Create more temporary batch files. Add
REM * more command line parameters if necessary,
REM * as in: ECHO SET USRINPUT=%%3 %%4 %%5 %%6 %%7 %%8 %%9>CURRENT.BAT
ECHO SET USRINPUT=%%3>CURRENT.BAT

REM * VOER.BAT and TYP.BAT are replacements for CURRENT.BAT for Dutch
REM * DOS versions; add your own language versions if necessary:
ECHO SET USRINPUT=%%6>VOER.BAT
ECHO SET USRINPUT=%%4>TYP.BAT

REM * This temporary batch file now sets the variable USRINPUT:
CALL %TEMP%.\~USRINP.BAT

REM * Display the result:
ECHO You typed: ←[1m%USRINPUT%&larr;[0m
ECHO.
PAUSE

REM * Finally, clean up the mess of temporary files:
FOR %%A IN (%TEMP%.\~USRINP.BAT %TEMP%.\~USRINP.TMP VOER.BAT TYP.BAT CURRENT.BAT) DO DEL %%A

←是escape character (27h)

Firefox直到Windows 2000或NT才被引入。旧版MS-DOS或等效版本将没有它。 https://www.computerhope.com/sethlp.htm

Answer 3

CMD和DOS非常不同。诸如command.com之类的DOS解释器无法使用set / a或set / p设置变量。但是，您可以尝试以下方法：

@echo off
echo Input:
for %%a in ('type con') do echo %%a >tmpinput.txt & goto next
:next
echo Output:
for %%b in ('type con') do echo %%b >tmpoutput.txt & goto next2
:next
set in=<tmpinput.txt
set out=<tmpoutput.txt
del tempinput.txt
del tmpoutput.txt

它将在command.com中真正起作用。它也可以在cmd中工作，但是我不建议在那儿使用。

使用标签的另一种方法：

FOR /F "tokens=5* delims= " %%A IN ('VOL C: ^| FIND "drive C"') DO SET OLDLABEL=%%B
ECHO Enter some input string, containing no more than 32 characters:
FOR /F "TOKENS=*" %%? IN ('LABEL C: 2^>NUL') DO SET INPUT=%%?
ECHO %INPUT%
LABEL C: %OLDLABEL% >NUL 2>&1

无法在DOS中输入变量
