heh heh.. You got that right.
I have seem way too many programs from way back then where the
programmer wanted to process every record in the file, or very nearly
so, and chose to process the file in Keyed order. There is usually no
reason for that; by processing it in arrival order performance improves
to where users wonder if the program actually ran.
Whether he is updating detail records, the primary records, or whatever
the case, unless there is a specific and clear reason to use the K, why
use the K? Programming is easier and performance is better.
At least, that is my experience.

What you are essentially saying is that if you use the RRN to read a
record from the file, then you'll know what the RRN of the record you
just read is. :-)
