u mean that in stead of putting the for loop variable 'I' put 0 and it will work out side the for loop like that
%~f0
instead of
%~fI inside the for loopQuote from: .bat_man on April 09, 2008, 02:50:52 AM

You use letters of the alphabet %%a to %%z and %%A to %%Z for loop variables and you use figures %1 to %9 for parameters PASSED to the batch file from the command line. %0 has a special meaning, it expands to the batch file's own name.
thanks a lot
i appreciate ur help
