Shifting variables in for /f

Hi, I need help with this one. I want to shift variables in a for /f loop. For example for /f "tokens=1,2,3,4,5,6,7,8,9 delims=:" %%a in ('@echo %trk%') do echo %%a %%b %%c %%d %%e %%f %%g %%h %%i (%trk% may contains something like 1:2:4:6:7:8:12) So instead of writing code to handle all the %%a to %%i variables I prefer to use a shift like method to process %%a only. This also helps to avoid extra code to handle how many variables have data inside.

here's a vbscript. Although its entirely up to you, i would recommend you learn about it, if you want to do scripting/batching on Windows.
strData = "1:2:4:6:7:8:12"
ArrData = Split(strData,":") 'split on ":"
For i=LBound(ArrData) To UBound(ArrData)
'Print out the elements.
WScript.Echo ArrData(i)

Thanx for the vbscript. The thing is that although i know vbscript (and as you demonstrated its a nobrainer to do the job) this specific script must be written in dos batch :-((

What about:
for %%a in (%trk::= %) do (
REM your stuff with %%a
)
If you variable contains <, >, |, ^, ;, =, a comma or tab it won't work as expected, since you only have numbers it shouldn't be a problem.
