I think you'll need to change the data type of the output field. 
Whenever I extract data I do it through a function, using a record type 
as the return type. With Paradox I redefined text as varchars in the 
output and I didn't have any problems.

Although I used to use in memory tcursors only for reference type 
tables, not often for data.
