Mark,
The post was not specifically about RDBMS back-end. This is obvious that many people around including myself are intelligent enough to know that SEEK() can be used for native VFP engine only and cannot be used for RDBMS. Sorry, that I have to tell you these facts now.
The problem (if we are still on technical groud) is that a developer cannot design his/her system blinfolded. It means that the first responsibility to assess scope of project, and if situation assumes that VFP interface will use native data, then this developer must use the most efficient way to develop this system. If someone does know what is SEEK about, then 'future upgrade' to RDBMS is really lame excuse.
