Change variable in batch file for-loop

Question

I have created a code that takes the following variables:

SET sdir=T:\path\to\in\
SET tempdir=T:\path\to\tempBatch\
SET list=DE NL

Then, I try to loop through the list items and copy all TXT files in them to the tempBatch folder.

(for %%l in (%list%) do (
    set tempINdir=%sdir%%%l
    echo %%l
    echo %tempINdir%
))

The output I get is:

DE
T:\path\to\in\NL
NL
T:\path\to\in\NL

Of course, I want to have the %%l variable concatenate with the %sdir% path:

The output I get is:

DE
T:\path\to\in\DE
NL
T:\path\to\in\NL

Why does it only take the last item in the list when creating tempINdir? I have tried to use setlocal EnableDelayedExpansion from this answer, but this doesn't do anything.

enabling delayed expanison is not enough. You also have to use it: echo !tempINdir! — Stephan

@aschipfl, as said in the question: that answer did not help me. — Nander Speerstra

The linked answer perfectly demonstrates both to enable and to use delayed expansion in order to resolve exactly the same problem... — aschipfl

As explained in the comments by Stephan and in this answer:

Delayed variables are referenced with !var! instead of %var%

So, in the for loop you need to use !var! instead of %var%.
