Array * and big array

I need to create an array pointer that point to a DS that has an array
in it.  Below is what I came up with.  

D listMast        s               *   dim(512)                    
                                                                  
D list            ds                  based(list_p) qualified     
D  lastElem                      5i 0                             
D  item                         50    dim(10000)                    
                                                                  
 /free                                                            
                                                                  
  listMast(1) = %alloc(%size(list.lastElem)+%size(list.item)*100);
  listMast(2) = %alloc(%size(list.lastElem)+%size(list.item)*100);
  *inlr = *on;                                                    
                                                                  
 /end-free                                                        

Question:
Above will not compile because list.item is too big.  Is there a way to
get around this?  I know I can get around it by taking item array out of
the list DS.  However, that kind of break my listMast idea.  Any
suggestion?
