There were various versions of VPD but one of the first for the 16-bit AOL 3.0 client was v.50a. 50a supported the ability to browse any AOL form and look at the FDO scripting of it. Now this was possible using Atomic Debugger, however, Atomic Debugger’s atom trace feature was very buggy and the program usually crashed when opening large forms.

VPD 50a was what made it possible for Lithium Node and others to get a real grasp of the FDO language. Without this tool it would have been near impossible for anyone to have had an understanding of FDO prior to the discovery of the Star Tool for 32-bit AOL clients in 1999.
