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

Subject: 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?
