为什么我的变量不能正确扩展

Question

我正在使用bat文件来处理数据库，我的变量没有正确扩展。

编辑：

我已经尝试了上述暂时还没有这样的运气。

这是必需的所有节目的代码：

set n=0 

:1 
echo. 
set /p fname=Enter First Name: 
set /p lname=Enter Last Name: 
set /p val%n%=Enter E-mail: 
set /p num%n%=Enter Phone Number: 
set /p var%n%=Enter Service Number: 
set /p dvice%n%=Enter Device: 
set /p dserv%n%=Enter Date Serviced: 
set /p summ%n%=Enter Summary of Service: 
@echo set var%n%=!var%n%! > "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
@echo set val%n%=!val%n%! >> "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
@echo set fname=%fname% >> "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
@echo set lname=%lname% >> "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
@echo set dvice%n%=!dvice%n%! >> "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
@echo set dserv%n%=!dserv%n%! >> "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
@echo set summ%n%=!summ%n%! >> "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
@echo set num%n%=!num%n%! >> "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
@echo set n=%n% >> "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
echo. 
echo The data has been stored! 
echo. 
pause > nul 
goto start 

:2 
echo. 
echo LAST NAME IS CASE SENSITIVE! 
set /p lname=Please enter last name: 
echo. 
if /i not exist "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" (goto Error) 
call "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
echo First Name: %fname%  
echo Last Name: %lname% 
echo Device: !%dvice%%n%! 
echo Date of Service: !dserv%n%! 
echo. 
echo E-Mail: !val%n%! 
echo Phone: !num%n%! 
echo. 
echo Summary: 
echo. 
echo !summ%n%! 
echo. 
pause > nul 
goto start 

这是我所有的工作。 ％lname％.bat将变量存储为var0 =“变量值”问题在于它不读取var0。它读取！var 0 !.

Answer 1

调用脚本时，cmd的新实例正在运行。变量集仅适用于该实例。

set filepath=C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat 
for /f "delims=" %%a in (%filepath%) do %%a 

通过%lname%.bat每一行这将循环和运行线作为命令 - 如果所有在%lname%.bat行的是那些组命令，这应该工作。

Answer 2

@ECHO OFF 
SETLOCAL ENABLEDELAYEDEXPANSION 
SET /a n=0 
:: call "C:\Documents and Settings\Administrator\Desktop\My Personal Files\Computer Refresh\Database\%lname%.bat" 
:start 
call :plname 
echo First Name: %fname%  
echo Last Name: %lname% 
echo Device: !%dvice%%n%! 
echo Date of Service: !dserv%n%! 
echo. 
echo E-Mail: !val%n%! 
echo Phone: !num%n%! 
echo. 
echo Summary: 
echo. 
echo !summ%n%! 
echo. 
SET /a n+=1 
IF %n% lss 2 goto START 

GOTO :EOF 

:plname 
SET "fname=First name read" 
SET "lname=Last name read" 
SET "dvice0=Device zero" 
SET "dvice1=Device one" 
SET "dserv0=Date zero" 
SET "dserv1=Date one" 
SET "val0=Email zero" 
SET "val1=Email one" 
SET "num0=Phone zero" 
SET "num1=Phone one" 
SET "summ0=Summary zero" 
SET "summ1=Summary one" 
GOTO :EOF 

这批证明你的代码确实有效。问题出在您的%lname%.bat，您尚未发布。当然，您不会为每个客户设置不同的%lname%.bat？

发布一些实际样本数据没有任何伤害 - 只需更改名称以保护有罪。将实名修改为“Brown”或“Green”或“Robinson”。似乎没有人再使用这些名字 - 他们显然是假的。
