Walden, they're not even _likely_ to be contiguous in memory.

Since the actual storage for parameters belongs from the caller,
the layout of the storage depends on the COBOL program.  But
you can't count on any storage being contiguous unless it's
actually in a data structure; this is true of any language.
If the storage for those parameters was already contiguous, you
wouldn't need this RPG program.
