In for loop, how to pass variable from one setlocal to another

[sincos2007]

Code: Select all

:test1
setlocal EnableDelayedExpansion

set "source_bat_file=txt1.txt"
for /f "delims=" %%i in (%source_bat_file%) do (
   rem echo %%i

   setlocal DisableDelayedExpansion
   set "line1=%%i"
   echo 1: %line1%
   endlocal&set line1=%line1%

   setlocal EnableDelayedExpansion
   echo 2: !line1!
   endlocal

   pause
)

endlocal
goto :eof

The first setlocal is for preserve content like !var1! from input text file.

Thanks

Wrong way. Keep the FOR loop in an environment with delayed expansion disabled. Define your variable, then enable delayed expansion to output your variable.

Code: Select all

:test1
setlocal DisableDelayedExpansion

set "source_bat_file=txt1.txt"
for /f "delims=" %%i in (%source_bat_file%) do (
   set "line1=%%i"
   
   setlocal EnableDelayedExpansion
   echo !line1!
   endlocal
   
   pause
)

endlocal
goto :eof

Will it cause: “reach max recurse of setlocal” error?

As long as you include ENDLOCAL for every SETLOCAL within the FOR loop, then the code will work fine without any recursion limit being reached.

But if you forget the ENDLOCAL, then yes, you can get that error.
