Del / Mark duplicates

[sbcglobal]

I have some VB like below, to delete duplicate. The Access table is 'RED',
key index field is 'Index', the VB nevigate through all records in 'Index'
and delete duplicate if found.

There are 2 problems:

1. I have to sort key field 'Index' first before del, since the sub only
compare adjacent 2 recordsets. Is there any other way to do this? Or how
would I sort records in VB?

2. Instead deleting, I'd like to name another field called 'Duplicate'
(yes/no). Can I modify below VB to mark field 'Duplicate' to 'yes' or 'no',
to indicate this is duplicate record (or not)?

Note if there are 5 recordsets in 'Index' have value=12135, then I ONLY need
to mark the first one (in field 'Duplicate') 'No', and rest 4 records 'Yes'.

Many thanks,
