QUEUEDJOB Table

Can anyone please tell me what the FILLER2 column of the QUEUEDJOB table is used for?  When I query the table for all possible values I get ?, ", #, and spaces.  It must mean something but I cannot determine it on my own.

In particular, the '#' are of interest because I am writing a query that lists jobs in the waiting queue and I am getting more than are really there.  When I omit those with the '#', it comes out perfect.

Any help would be greatly appreciated.   Thank you very much!
