Alphabetizing detail records to a header file

I have an idea I may have missed something obvious.

Here's the situation:  I have a Header File of names and addresses. The
Header File has a unique identifying number for each name.  The numbers
are assigned as each new name is added to the file so the numbers really
amount to arrival sequence, not  to Alphabetic Sequence.   I do have a
logical over the Header File based upon the name, so that any reports can
be generated in alphabetic order.  All this seems simple and straight
forward.

Now comes the part where I think I am missing something:  I also have an
application with a small detail file for a  specialized application.  The
small group is probably going to be about 300 records but certainly never
over 1,000 records.  I've linked it logically with the Header File by the
unique Header File I.D. number. To present an alphabetic subfile on the
screen of that small grouping I have to read through the entire alpha
logical on the Header File.  As you can imagine performance is horrid.

In the past I've loaded an *INZSR array, and I've denormalized the data.
Neither method has felt right.  Is there some simple thing I've missed?

Thanks.
