Do Batch files support multiline variables

Question

If so How?

Yes, batch files are lame, but I cannot use powershell, and I don\'t feel like writing a real app to do this simple task....

If you wanted to build something instead, not just outputting, hope this would be useful to you too.

Firstly, you should make a file. Such as .txt. I'm going to use var.txt as an example.

Secondly, type in the multi-lines of variables.

Thirdly, here are the codes, but only works for batch:

@echo off
set num=0
set /p this%num%=<"var.txt"
goto there

:there
set /a num=num+1
for /f "skip=%num%" %%a in (var.txt) do (set this%num% =%%a
goto there)
set num=0
goto build

:build
rem Example of using multi-lines of variable.
call echo %%this%num% %%
set /a num=num+1
for /f "skip=%num% delims=" %%a in (var.txt) do (call echo %%this%num% %%
goto build)
rem Just replace the commands with `echo` part into something else which suits your situation.
pause >nul
exit

I admit that strictly speaking, this is not a variable of multi-line, but in my opinion, this is better than nothing.

You may ask why not just use the setlocal EnableDelayedExpansion command. The reason is simply, that command does work for me (IDK why). Therefore, I thought and made these codes that make the same effect.
