Well, I should point out something that may clarify my point: all my input/output is concentrated in a unit of functions and objects which interface with flat files, so my programs do never deal directly with files. In a manner, I've emulated a database system with search and report tools. One last point: in Argentina, my system (complete application) sells for approx. 8,000 , while an Oracle configuration alone (without any application) would sell for 12,000 !

Sorry for the thread shift - ok, we were talking about worms.

Un abrazo - Andrés
