RE: Overlaying fields within a data structure with an array

I've never tried it (or had the energy to look it up), but could you use a
PREFIX keyword on the file DS similar to what you do on an F-spec? Or could
you qualify the file DS? (Never tried that one either.)

Yes, that is what Jerry suggested to do. Just one problem with this
approach: you can no longer define the file ds on that program. So, if some

how some one needs to define the entire file structure as DS in that
program, then he is out of luck.

Actually, if you're doing traditional RPG scatter-gather I/O, then the
relationship between the fields in the file shouldn't make any difference
if you redefine the fields to make them contiguous in a DS.
