Sorry..got really swamped at doing other things at work, plus, had several days of snow delays

It gives me "Thread X terminated abnormally: Invalid value for shared scalar at S:\Reports\NotWorking\Stats5c.pl line 594, <DATA> line 335"

<\p>

It's probably a warning -- in that it doesn't outrightly die on me.

Which of course means the hash population which this is supposed to be changing is unpopulated when it returns...

In my 'fiddling' with Threads::Shared, I wongled together a means of doing a single variable and field combo

which seemed to work...

I may have to, while not ideal, split the %data hash into 2 or 3 hashes -- one part for the shared pieces (using a split-able string single level hash) and one for the unshared portions. And presumably use split to re-merge the shared portions back.

There are many anomalies in your OP code.

For example, you have many blocks of code like this:

                unless (exists $$dataref{$eid}{"ALL"}{"MatchesPeopleEn
+ded"}){
                     my %a :shared;
                     $$dataref{$sid}{"ALL"}{"MatchesEnded"}=\%a;
                }

Note that you are testing exists $$dataref{$eid}{"ALL"}{"MatchesPeopleEnded"})

But are assigning to $$dataref{$sid}{"ALL"}{"MatchesEnded"}=\%a;

That probably explains your immediate problem. However, there are further anomalies.

For example, why are you assigning references to shared hashes to a bunch of variables that you subsequently are using as integers:

            $$dataref{$sid}{"ALL"}{"MatchesStarted"}++;
            $$dataref{$sid}{"ALL"}{"MatchesPeopleStarted"} += $tn;
            $$dataref{$sid}{$whichco}{"MatchesPeopleStarted"} += $tn;
            $$dataref{$sid}{$whichco}{"MatchesStarted"}++;
            $$dataref{$eid}{"ALL"}{"MatchesEnded"}++;
            $$dataref{$eid}{"ALL"}{"MatchesPeopleEnded"} += $tn;
            $$dataref{$eid}{$whichco}{"MatchesPeopleEnded"} += $tn;
            $$dataref{$eid}{$whichco}{"MatchesEnded"}++;

Part of your problem is that you spread your code around all over the place which means that you need to scroll up down many pages to see where a variable is declared, initialised and then used.

There is a huge chunk of code in the middle of your program that I suspect could be replace by this:

                    $$dataref{$sid} //= &shared({});

                    $$dataref{$sid}{"ALL"} //= &shared({});
                    $$dataref{$sid}{"ALL"}{"MatchesStarted"}++;
                    $$dataref{$sid}{"ALL"}{"MatchesPeopleStarted"} += 
+$tn;

                    $$dataref{$sid}{$whichco} //= &shared({});
                    $$dataref{$sid}{$whichco}{"MatchesPeopleStarted"} 
++= $tn;
                    $$dataref{$sid}{$whichco}{"MatchesStarted"}++;


                    $$dataref{$eid} //= &shared({});

                    $$dataref{$eid}{"ALL"} //= &shared({});
                    $$dataref{$eid}{"ALL"}{"MatchesEnded"}++;
                    $$dataref{$eid}{"ALL"}{"MatchesPeopleEnded"} += $t
+n;

                    $$dataref{$eid}{$whichco} //= &shared({});
                    $$dataref{$eid}{$whichco}{"MatchesPeopleEnded"} +=
+ $tn;
                    $$dataref{$eid}{$whichco}{"MatchesEnded"}++;

Which might improve things a little, but I have no way to test that.
