>When you are editing a class or form, you can select Edit Property/Method... option under the Class/Form menu pad. On that options form, you can add a description for your own properties or methods. I can not find anywhere where this is documented on how to add a description programmatically. Is this possible? FWIW, this description info is stored in the Reserved3 field of the VCX or SCX. TIA!

Only by direct replacement of that memo field. There's no "method" to provide a description.
