hummm... it wouldn't be the first time that i've not groked what the error 
messages were trying to tell me... that's why i decided to try this vector 
instead of the failed attempts to create another opbject based on the original 
and inherit the procedures with a replacement of this particular one...

hummm... the original has no parameters at all... my addition has two... will 
this be a problem? no, i've not had a chance to get back to the development 
machine and try :?
