How to continue the effect of "setlocal ENABLEDELAYEDEXPANSION" after "endlocal"?

Here are two batch files : 1.bat, setenv.bat
1.bat:
call setenv.bat
echo %var%
setenv.bat:
setlocal ENABLEDELAYEDEXPANSION
...
for ... do (
if ... (
set var=!other!
)
)
endlocal
delayed expansion is needed in setenv.bat for some reason. setenv.bat is used to set some environment variables, which used in other files, 1.bat here.
But even if var is set in setenv.bat correctly, 1.bat still uses the old value of var: Say var=old before calling setenv.bat, and setenv.bat change the value of var to new, but the output of 1.bat is still old, which I need it to be new.
Any way to gain the effect of delayed expansion without localizing the in-course modification?

At the very end of setenv.bat:

...
endlocal&set "var=%var%"&set "var2=%var2%"

You can try FOR /F to keep your variable:

setenv.bat:

setlocal ENABLEDELAYEDEXPANSION
set other=new
...
for /f "delims=" %%V in (""!other!"") do (
 endlocal
 for ... do (
  if ... (
   set var=%%~V
  )
 )
)
