Transform for Lookup Close window button

FileMan uses this transform only during lookup.

The contents of this transform should be M code that sets the variable X to a new value. X is the only input variable that is guaranteed to be defined and is equal to the lookup value entered by the user.

During lookup, if the lookup value is not found in the index, FileMan will execute the TRANSFORM FOR LOOKUP code to transform the lookup value X. It will then search this index looking for a match to the transformed lookup value.
