RE: v5r2 enhancements for Keyed I/O

The documentation for the chain op code does list files or record formats.
However the description of %KDS only references record formats.  Because the
keyed data structure you have defined is built over a specific record format
the chain must have the corresponding format.

When using a data structure to replace a klist, I get a compile error if I
use the file name.
Using the record format name when using a data structure works.

I was just wondering if this is correct or if I might be missing something.
