And to eliminate the hardcoding of the dimension:

     D  MaxPtyAlpha                  
     D   MaxPtyA                           Overlay(MaxPtyAlpha)
     D    MaxPty1                    10i 0 Overlay(MaxPtyA:*next)
     D    MaxPty2                    10i 0 Overlay(MaxPtyA:*next)
...
     D    MaxPty8                    10i 0 Overlay(MaxPtyA:*next)
     D    MaxPty9                    10i 0 Overlay(MaxPtyA:*next)
     D    MaxPty                     10i 0 Overlay(MaxPtyAlpha) 
     D                                     Dim(%Div(%Size(MaxPtyA)
     D                                             :%Size(MaxPty1)))
