I am try to access a environmental variable i SET inside the batch for loop. But i can't seem to acess it even tho its actually already existed (i pause the forloop and test it on anther cmd screen).
Can anyone please help me about it?

Below is the script.

:: I name my usb hard disk with bracket, ie.(hard-disk-Name)
::-----------------------

for /f "token=2 delmis=(*)" %%A IN ('vol e: f: g: 2^>NUL') do (
SET hd_name=%%A
echo %hd_name%
)

::-------------------------

I couldn't make yours work, so I re-wrote it.

Note that the variable is NOT available in a different command shell.

:::::::::
@echo off

for /f "tokens=*" %%A IN ('vol c: e: u: ^|find "drive"') do call :sub1 %%A
goto :eof

:sub1

SET hd_name=%6
echo %hd_name%
goto :eof

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

I think the problem is whenever i try to do arithmatic inside () , it just won't work!

I try this and somehow the line outside bracket give me correct answer and inside 1+1 always give me 1 not 2...

SET ROT_COUNTER=1
if %ROT_COUNTER% LEQ 2 (
SET /a ROT_COUNTER=%ROT_COUNTER%+1
echo "ROT_counter less or equal to 2"
echo %ROT_COUNTER%
) else (
SET /a ROT_COUNTER=1
echo %ROT_COUNTER%
)

SET /a ROT_COUNTER+=1
echo %ROT_COUNTER%

SET ROT_COUNTER=
