How do you access the remote data?
If you are using views, you should be able to change the data type of the logical fields in the views to "L" with DBSETPROP().
Then the view would handle the conversion (1=.t., 0=.f.)
I don't have Oracle to test, but I believe that's the way it's supposed to work.

If you do have to make changes in VFP, I would make it in code to make a False check be Empty(field) and a True check to be Not Empty(field). Then you don't have any conditional programming to do.
