CHAIN vs SETLL/READE

The intent here is to fetch the data record.

Actually there are 2 separate conditions: For one file, the record would
mostly be found, for other it would mostly not be found (I still need the
data whenever it is found).

Would the recommendation be different in these 2 cases?

Changing up the question like this is useful.

Regardless of the choice taken in your first case, in this second case, you want to make the code almost redundant.
The blocks should be perfect copies of each other.
This is so the programmer coming behind you sees them are identical logic blocks.
Do not do anything different "for efficiency" or "for style" in the two different cases if it takes his eyes and mind 10 or 20 or 30 seconds to view the blocks
and understand your intent and assure himself they are satisfying that same intent.

You don't want him to have to ask himself, "why did that guy do it that way?" when he sees two different ways of coding the same process.
