I guess something like the comment line that appears when you edit an ActiveX, _access or _assign method, so when you subclass your own class and start editing a method, a comment line explaining the parameters would appear?

Not sure that's possible, but with VCXes at least you get the lParameters line automatically inserted - so, try to make the parameter names meaningful.

Update: solved it! Add a && comment at the end of the parameter line, and it will be repeated when you subclass. Tried in 9.1.
