Re: CHAIN Versus SETLL and READ When Data Needed

Agreed, but the general rule I always follow is to go from strictest to least restrictive. If I want red-haired girls that live in NYC I will start testing/filtering on red hair, then NYC, then girls. Not much sense in checking gender and city and then fail the test on hair color.

Usually when you do this type of coding, it's because you know (from reviewing the file) all the key fields won't always be there.
The answer is to review the file and determine which key configuration will occur most often, then code the chains accordingly.
