How can I echo nested variables inside a for loop?

Question

Here is a for loop to save each line of a text file to its own variable:

@echo off 
setlocal enableextensions enableDelayedExpansion 

set count=0
for /f "tokens=*" %%a in (file.txt) do (
    set /a count=!count! + 1
    set var_!count!=%%a
)

endlocal

I would like to save the content of each variable to a separate new text file. How can I do this? I tried the following. But it does not work, because !var_!count!! is a variable inside a variable.

@echo off 
setlocal enableextensions enableDelayedExpansion 

set count=0
for /f "tokens=*" %%a in (file.txt) do (
    set /a count=!count! + 1
    set var_!count!=%%a
    echo !var_!count!!>file_!count!.txt
)

endlocal

@echo off 
setlocal enableextensions enableDelayedExpansion 

set count=0
for /f "tokens=*" %%a in (file.txt) do (
    set /a "count+=1"
    set "var_!count!=%%a"
    for %%b in (!count!) do >file_!count!.txt echo !var_%%b!
)

endlocal
