These variables are DEFINED IN THE REPORT, I'm trying to access them in a object that is called by the OnEntry bands of the report. Before SP2 all Report Variables were defined as Global, now I can't find them. The only work around I have been able to do is to create another Report Variable and set the Value to Store expression: _Vfp.SetVar("ldBgn", ldBgn). I have over 500 reports to check. And I don't have a way to delete the public variable after report is finished running (yet).
