Tom,

You understand me correctly - I am looking at ways of realizing the 3-tiered "dream".
I (think) I have a good grasp of the basic *concepts*, but it is in VFP's implementation potential and in the capabilities/limitations of OLE that my questions lie.

I think it would be innovative and extremely useful if the next version of VFP supported some mechanism to permit VFP-to-VFP of views and SQL and general record-set capabilities with the full power of 'local' VFP.

Thanks,
Jim N.

Am I missing something here - that is, are there ways for one VFP (client) to 'request' a set of records from another VFP process (server) on another machine USING STRAIGHT VFP COMMANDS???

Also, in this situation, I *ASSUME* that OLE and other functionality "takes care' of keeping track of sender/recipient and that VFP Server need not concern itself with those duties. Would that be a correct assumption?
