I have the following code:

setlocal enabledelayedexpansion
for /L %%i IN (1,1,5) do (
    set /A is_echoing=0
    if %%i==2 (set /A is_echoing=1)
    if %%i==5 (set /A is_echoing=1)
    if %is_echoing%==1 (
        echo Hello World
    )
)
endlocal

It is giving me an error:

( was unexpected at this time
                    if ==1 (

It seems the variable is_echoing is not set in the for loop. Why is this the case and what can I do about it?

See [this answer](https://stackoverflow.com/a/10558905/62576) for an explanation. – Ken White Dec 21 '20 at 03:49
Thanks, I have included setlocal enabledelayedexpansion, so that is not the issue. – ablan Dec 21 '20 at 03:53
But you're not using it, because you're still using `%%i` inside the loop. Read it again. :-) – Ken White Dec 21 '20 at 03:55
Hmm, not sure I get it after reading the 5th time, so I should use !!i instead? – ablan Dec 21 '20 at 04:04
The second code block in that answer demonstrates the proper use of `!`. In your case, it would be `!i!`. – Ken White Dec 21 '20 at 04:08
Oh I see, I get it now, thanks a lot! – ablan Dec 21 '20 at 04:15
