Beginning to learn about private datasessions ---

I have a problem with the interaction of two forms, both of which have private datasessions.

Form A shows a grid with calculated data for all parts in our system. All parts are assigned a "class ID". There is a simple cursor which allows the user to select which class IDs are visible. (Only two fields in this cursor: class ID and Y/N flag).

The user can invoke Form B from a pop-up menu. This form contains the relevant information which is editable for each part.

What I'd like to be able to do is to have the list of items in Form B that appear to be the same as those as the user saw on Form A. I don't know how to do this, as I don't know how to pass my simple two-field cursor from Form A to Form B.

Suggestions?

Thanks,
Jim
