Re: DDS arrays

["Eric N. Wilson" <doulos1@xxxxxxxx>]

Jim could you not define it in the following manner?
D ArrPtr   S                *             INZ(%ADDR(FieldinRecord))
D D6        S              9  0          Dim(6) based(ArrPtr)

I think this would work for you. I do not have a connection to a 400 right
now to compile it but it should get you close.
