Sorting DBASE tables via two indices

[drdispatch]

I need to link a table to a master table via a primary index while still allowing sorting by a secondary number. example:

key1 key2
1 1
1 2
1 3

I need the ability to have the user reorder the key2 fields, say by changing the 3 to a 2 and the 2 to a 3, etc.

Any help will be greatly appreciated
