Re: unexpected busy flag declared

Hi Pietro,

I was trying to investigate your problem, but I see far too many C++ programming bugs in the code

  -non-declared variables
  -use of arrays where a scalar is expected
  -etc

I started to modify your code, but nearly every line needs to be modified. In my modifications (see attachement) you will see that I use ACLIC to compile your code. This will produce better dignostics than CINT. I suggest you start from this code to see the list of problems reported by the compiler.
