Re: [Condor-users] Pushing ClassAds into theenvironment forrunningjobs?

You can read about $$() expressions here:

http://www.cs.wisc.edu/condor/manual/v6.6/condor_submit.html#36286

In short, it should do precisely what you want.  However, I've heard 
reports that $$ substitution got broken in the development series 
(6.7.0-6.7.2).  This problem will be fixed in the next release.  Sorry!
