Using Alpha Order with fileset local

New to using fileset local on an inbound thread in Cloverleaf. Have selected Alpha Order and my set of input files is named TestA, TestB, TestC.

In stopping the thread before the process is done, I see that it appears to be processing the files in reverse alpha order – i.e. processing TestC first, followed bb TestB and lastly TestA.

Seems odd to me – any ideas on why it is doing essentially a reverse alpha order? Can’t see anywhere to specify this.

Thanks,

Janet
