Once again, that is just my guess, I'm sure someone knows, I just don't pay attention to those things. You are using SQL SELECT to build this cursor, right?

>AFields would let me re-construct the cursor in local app, but I still need to load the cursor after requerying the COM server with a parameter.

WHat do you mean "load the cursor." Build the structure or give it data? How is it different between the Local App and COM Server (Sorry, I just haven't done enough with COMs to know).

To build a cursor using AFields(), you can do this:

AFields(laArray)
create cursor TempCursor from array laArray
