Hi all! Probably a silly question, but I'm rather new to batch programming and the following just doesn't make sense to me at all!

@ECHO OFF
SETLOCAL
SET CNTR=0
FOR %%i IN (one,two,three) DO (
SET /a CNTR=CNTR+1
ECHO %CNTR%
)
ECHO %CNTR%
GOTO :EOF

I'm expecting the output to show
1
2
3
3

but I get
0
0
0
3

There's obviously something I don't get about defining and using variables... Any help appreciated!

... OK don't worry, I got it! (EnableDelayedExpansion)

sorry for wasting space!

For simplicity, you can skip onotialing the var.

And increment like this:

::==
@echo off
setLocal EnableDelayedExpansion

for %%a in (one two three) do (
set /a cntr+=1
echo !cntr!
)
echo !cntr!

=====================================
If at first you don't succeed, you're about average.
