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. HTH ::::::::: @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.

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=
