FNDSRC – Find Source Code for any object in IBM i
(and yes it works on old AS400 and iSeries Systems as well)
The Projex FNDSRC runs of a database (built on a regular schedule defined in the IBM i Job Scheduler) of all source members on the system.

So it can look for generic source members anywhere on the box– which I find really useful hunting down rogue source.
FNDSRC MBR(PROOF*)
Will show all source members beginning with PROOF*
