If the file is an externally-described file, search-arg can also be a composite key in the form of a KLIST name, a list of values, or %KDS.

So, you can list the key fields in a KLIST, or you can list them in the CHAIN instruction itself, or  you can list them in a key data structure. The language reference manual is where you should find answers for questions like this one.
