Christof,

Here's another infelicity of teh WITH/ENDWITH construct that I got bit by. The object reference is resolved on the WITH line and it is not refreshed later;

GO TOP
SCATTER NAME MyData
SCAN
   WITH MyData
       .Name = "Joe Smith 1"
   ENDWITH
   GATHER NAME MyData
   SKIP
   SCATTER NAME MyData
ENDSCAN

The above code will only change the first record because it loses the reference to MyData after the first pass.
