echo off

set /a a=0
:start
if %a% LEQ 21(
echo test

I only get a Syntax-error when the loop starts.

    You are missing a space between 21 and ( which will make it compare the number in the loop to 21(, also breaking the if statement, the latter being why you are getting a syntax error.

    Add a space and it works fine.

    echo off
    
    set /a a=0
    :start
    if %a% LEQ 21 (
    echo test
    set /a a=%a%+1
    goto start
    )
