Re: READE with partial key

[Booth Martin <booth@xxxxxxxxxxxx>]

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?
