unable to employ variables created in batch script Bamboo task

Question

For /f "tokens=2-4 delims=/ " %%a in ('date /t') do (set thedate=%%c_%%a_%%b)
echo %thedate%
mkdir C:\Users\avalencia	est2\${system.thedate}_${bamboo.custom.svn.revision.number}
xcopy.exe TechServiceTool\TechServiceTool\bin\Release C:\Users\avalencia	est2\${system.thedate}_${bamboo.custom.svn.revision.number}\ /e

per build log, date evaluates correctly in the first line (set thedate=%%c_%%a_%%b), but is not usable in the lines afterward.  how can I use thedate batch variable after it is correctly set in the first line.  the goal is to have  the date in a specific format to use to create a directory in which to put the build.  i'd rather not create an msbuild or ant file just for this.

I never could get system variables to work either.  I use the injection plugin as a work around.  Clunky but it works. And specifically it was on the date.  Seems like a useful idea for an enhancement.  have today's date as a bamboo variable since so many of us use dates in folder names (to hold builds for deployment etc.)

xcopy, as it turns out, creates all intermediary directories, making the mkdir statement unneccessary.  the echo statement was there just as a test.  only one statement uses the variable.  so, i simply made that last statement my do body rendering the batch variable useless.  until somebody can figure out how to set batch variables in a script batch task, the solution to this problem is.

For /f "tokens=2-4 delims=/ " %%a in ('date /t') do (xcopy.exe TechServiceTool\TechServiceTool\bin\Release C:\Users\avalencia	est2\%%c_%%a_%%b_${bamboo.custom.svn.revision.number}\ /e)

yes.  i see where we're going with this.  i believe the svn var evaluates w/in the task prior to functional parameterization.  if not, then that will be the next barrier.  i really didn't want to have to check any build-specific files into SVN which accomplish such trivial tasks.  the script task, executable as a batch file should not be advertised as such if not the case.
