ah, what a wonderful application for the RPG cycle!

Forget the SET command, just use InputPrimary, leave off the K and race
through the file doing  If date > testfield.   If the numbers indicate few
deletions, then leave the K there, by date, and stop or start doing
something when the date threshold is crossed.

It'd be 3 or 4 lines of c-specs, max, plus the sub-routine for what is to be

Without the K and using IP, performance can be astonishly fast.

Subject: RPG/400 SETLL

Dumb Question

I still process some files via RPG READ loop after *LOVAL SETLL

I want to access a file by descending key & would you believe I have never
done that before via READ* variants?
I have got a logical of the records in descending sequence & I am not sure
my logic would be same pattern
ie. *LOVAL SETLL file then READ loop ("forwards" through the records)
or if I should *HIVAL SETHH at begeinning because I'm going to be reading

Reason for this is I want to flag the oldest entries for deletion & I
I would start at the beginning of the point I want to keep.
