>I don't see it in the version 7 help file.

In the VFP7 help file it is hidden. Look at the Contents tab and open:

Microsoft Visual FoxPro 7.0
Using Visual FoxPro
Developing Visual FoxPro Applications
Distributing Applications
Preparing an Application for Distribution
Removing Restricted Visual FoxPro Features and Files

You'll see a table of undistributable commands. In VFP8, it is in the remarks section of the APPEND PROCEDURE help page.
