This macro marks as duplicates any records that have the same value in a
field as the first record with that value. This macro illustrates how to:
- Loop over the records in sorted order
- Read a value from a field
- Find the first record in a group
- Write a value to a field
You can modify the macro to use a dialog box to get the values for the
input variable, mark members of a group with a counter (1, 2, 3, etc.), add
the duplicates to a selection set, etc.
