Re: READE with partial key -- RPG400-L

I think you're right.

I reran my test making sure that I set the date to *loval before each time
I hit this code section.

It still (seemingly) didn't do it in date order until I noticed that in
setting up this test data I keyed one of the dates as 2012 while all the
rest were keyed as 2013. Holy crap! How far into 2013 are we? I think I
need to go home for the day.

It read the item records in Date order (ie, key order) even though I know
for a fact that the physical order of the records does not match the key
order.

It wouldn't matter what the date was. If you do a setll on the file with
an ITEM then you will get the first record in the file for that item. If
the second key column in the index is a date then you will get the lowest
date that belongs to that item.

I do set the date to *loval before entering this part of the code. I just
neglected to show it here.

I'd be concerned that the date field is likely to be the highest date
from the last read cycle, not *loval. After the first read in the
program it is unlikely that he will ever find a record with a date
lower than the highest date read since the first cycle of the program.

I believe that as long as the f-spec for the file FILE is defined as

keyed, you SHOULD get the records in Item (ascending)

Date (ascending) order.

Suppose I have a file defined via DDL with unique key consisting of

Item (ascending)
Date (ascending)

// Set position in file
SETLL Item FILE;

// Only while this item
Dow '1';

Reade Item FILE;
If %EOF(FILE);
Leave;
Endif;

process record . . .

Enddo;

I am not assured of getting records within this item in ascending
Date

sequence, am I? Some testing I'm doing now shows that I don't.
