Generally, i want do do some operations to some vars in a loop, the number of vars may change, i tried a sample like this:
set header1=appdef1.h
set header2=appdef2.h
set header3=appdef3.h
set headers= "%header1% %header2% %header3%"
for /f "delims= " %%i in (%headers%) do echo %%i
pause
while it only output "appdef.h", confusing!
This should do what you want:
set header1=appdef1.h
set header2=appdef2.h
set header3=appdef3.h
set headers=%header1% %header2% %header3%
for %%i in (%headers%) do echo %%i
pause
Your original code passed just the 1 parameter as %%i, your fix passed them as %1, %2 %3 to :lable, which then split them out.
My code calls echo %%i once with each parameter.
c:\>set header1=appdef1.h
c:\>set header2=appdef2.h
c:\>set header3=appdef3.h
c:\>set headers=appdef1.h appdef2.h appdef3.h
c:\>for %i in (appdef1.h appdef2.h appdef3.h) do echo %i
c:\>echo appdef1.h
appdef1.h
c:\>echo appdef2.h
appdef2.h
c:\>echo appdef3.h
appdef3.h
c:\>pause
Press any key to continue . . .
header variables.Got the solution:
@echo off
set header1=appdef1.h
set header2=appdef2.h
set header3=appdef3.h
set headers= "%header1% %header2% %header3%"
for /f "tokens=* delims= " %%i in (%headers%) do call :lable %%i
goto END
:lable
if "%1"=="" (
echo the end
goto END
)
echo %1
shift
goto lable
:END
pause
