Windows batch file script IF does not work

Question

I have tried to make Windows batch file that blinking the word "Wait" & "Wait..". I tried the following code:

@Echo OFF
setlocal EnableDelayedExpansion
for /f %%a in ('copy /Z "%~f0" nul') do set "CR=%%a"
SET p=-1
set num=2
set st[1]=Wait
set st[2]=Wait..
set st[3]=eer

:LOOP

if /i %num% equ 1 (
set num=2
) else (
set num=1
)
<nul set /P "=!st[%num%]!!CR!"

TIMEOUT /T 1 >NUL






GOTO :LOOP

The problem here, the IF seems to be worked only one time. i.e running the batch makes it prompt "Wait" only one time, then "Wait.." forever. What is the mistake here?

You problem is not the if (that works as intended), your problem are the spaces that should delete/overwrite the dots.

set "st[1]=Wait  "
set "st[2]=Wait.."
