Sort of like externally-described data structures, eh?

I can see how this might simplify programming in some situations. But from
what I can see so far, you're still passing data back and forth to some
other procedure or program. It's just that the parameters are defined
within some I/O buffer rather than as separate variables.

Some have suggested this could be used to interface to other RDBMS's.
Unfortunately, RPG's I/O model (ISAM, more or less) doesn't really map
cleanly with SQL RDBMS's.

One positive effect so far is that this has gotten people talking about
RPG. I just hope, like others, that there's substance behind the hype.
