Re: READE with partial key

Here is where I am having trouble. Lets say that the file is uniquely
keyed by Item and SKU number. Lets say there are logicals defined by
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.
