Is there any documentation on ...\samples\classes\registry.prg?

(I am rather leery of tossing darts at my system's Registry.)

I have printed the program, and I see apparent references to
earlier versions of VFP 6. This raises the secondary question of
whether the program is up-to-date and will work.

Sincerely,

Gene Wirchenko
