RE: Two reade loops: which one preferred ?

I found this out the hard way too... CHAIN isn't equivalent to SETLL-READE.
READE sets the %EOF "indicator" if it doesn't find a record, but CHAIN
doesn't, it sets %FOUND (I believe). So if you want a single loop test, it
needs to be %EOF, and therefore CHAIN to initialize the loop doesn't work.

OK, I'm doing C these days and haven't done free-form RPG. Is CHAIN gone? 
Why the SETLL-READE combination, when CHAIN is equivalent?
