Unfortunately, that won't work.

Even if the vars usage you want worked at the DAG level, I don't think 
this would get you what you want.  If you're queuing 150 jobs, all with 
the same value for $(procid), all of your jobs will write to the same 
output file, which will mean that you'll only actually get the output back 
for whichever one finishes last; the earlier ones will be overwritten by 
the last one.
