Just an extension to previous mail:
The principle I described should work, but extend the system replacing 
site or clinic with date. To get all the old data recoded  (the 
following is not a nice way, but works):
0. turn off the "key unique in fldcontrol"
a. go to record 1.
b. press and hold enter key down until you have been through all records 
- this will recode the control field in existing data. (sometimes I put 
a pencil in the keyboard to lock the enter key).
turn on the "key unique" in fldcontrol
you should be working allright.
