Re: Mapping buckets in a record to arrays

For one file I'm not sure about 6

D               E DS                  EXTNAME(File1) Inz 
D @UNameit        S               *   Inz(%addr(firstbucketfield)) 
D UNameit         S                   like(firstbucketfield) 
based(@UNameit)
D                                     Dim(13) 
 * 

Thanks

        Subject:        Mapping buckets in a record to arrays


I have 6 files that each contain many sets of 13 buckets each. Is there a
way to define an external data structure for each file and "map" an array 
to
each set of buckets? I guess overlay might work, but I would have to
calculate the offset in the records for each array. Can I create an array,
based on a pointer, and initialize the pointer to the first bucket field
address? I seem to remember someone before having a problem with fields 
not
being contiguous in memory and that caused a problem.

Any help would be appreciated! Thx!
