ahhh! that helps to explain what the compiler error was that i was seeing... so 
i may need two different types if each procedure called from centralControl has 
different parameters? won't that cause a conflict if the parameters are not the 
same or are in different ordering or even if some procedure doesn't have 
parameters at all?
