RE: READE with partial key

I don't get where the confusion is supposed to be coming from. The OP
and everyone else who has replied to his question is talking about what
happens when doing a SETLL on a logical view with a partial key. Any
mention of SQL is just clouding the issue IMHO.

Here is where I am having trouble. Lets say that the file is uniquely

Item & color, Item & size, and Item & date.

If my program uses the logical of Item & Date and I SETLL on item

alone,

will I always get the lowest Item & Date record?

Yes. (If you define the file as keyed on the F spec.)

Booth -

As Birgitta implied, perhaps you are confusing RLA with SQL.

If Jeff was using an SQL cursor to retrieve the data, his select
statement
would necessarily need to include an ORDER BY clause which specifies
item
*and* date in order to ensure the proper sequencing.
