No, you don't want to index on the ID because it is unique.  That would be a 
very inefficient index.  If you created an i-descriptor that broke the ID into 
several multi-valued parts, then it MAY help, but I don't think it is worth the 
overhead.

Subject: [U2][UD] Index for @ID (IBM documentation)

Hi everybody,

In the IBM publication "Developing UniBasic Applications", Version
7.1, December 2006, it says on page 4-16 (page 93 in my PDF file):

                   Tip: Create an index for @ID to speed access to data records.

Seriously?  Will that honestly speed things up in a file that has
eight million records?
