Hi Barb,

A couple of sideways thoughts.

First, VFP works fine with Oracle. You would, with a varying amount of work depending on how your app works (does it use views), keep your VFP code working with Oracle. If you use tables, there is a documented way to use SQLEXEC and make the cursor updatable. Again, it depends on how the app was written.

Second, eTecnologia is 90+% complete with the VFP Compiler for .Net. They are not only allowing VFP code to compile to .Net, along with seamless use of .Net classes, but are also extending the the VFP language. One extension is the SQLUSE command, which will open a client-server table as though it is a VFP table, and allow all the usual actions.

I call these sideways thoughts because they aren't mainstream ("learn .Net; you'll be a better person for it"). They're McDonald's answers (as my wife jokes, if she is what she eats, she's fast, cheap and easy <s>), though, and there's a place for that in the real world.

>I do contract work for a client who has a suite of VFP applications that are used to maintain two main DBF tables. The names have about 800,000 records and the addresses about 450,000 records.
