This article is from the Programming VCOMM FAQ, by firstname.lastname@example.org (Taed Nelson) with numerous contributions by others.
The errors listed here refer to the online help files, but many (if not all)
also exist in the printed documentation.
Many of the documentation errors in the Microsoft documentation are shared by
VtoolsD, since much of it is copied verbatim or only slightly modified.

[Fixed in version 2.02.] The online help can be searched to find the entries
