Hi Rene - I don't explicitly call gROOT-Reset() in my selector. It's
pretty much the standard selector generated from TChain::MakeSelector(),
with a couple modifications that I don't think call gROOT->Reset().
However, when I do .g at the command line, I see (for example):
(compiled) 0x2ae4d680 const Int_t kMaxInt=2147483647
vs.
11 0x8733ca0 Float_t R2=0.607421
so my R2 variable doesn't have this (compiled) status. And I can print
out the value of kMaxInt from my selector. R2 is declared at the command
line (or via unnamed macro) - how do I get it into compiled status?
Thanks.
