... there is no "rule" relating the old values to the new values.
E.g., 101 replaced by 65687; 102 by 65686; 103 by 73128 and so on.
Thus, I can use:

recode id (101=65687) (102=65686) (103=73128) and so on

Alternatively, I can create another file containing information on the
new values of ID. Then, I match the new file and the original file.
--------------------------------------------------------------

With many values I would definitely create another file and then merge:

input permit permit2
101 65687
102 65686
103 73128
...
end
sort permit
merge permit using ...

Hope this helps
Svend
