Re: same options for 30 functions?

IF I understand the question, I have run up against a similar problem. I'm looking  
at array signal processing problems and, of course, all of the applications need to  
know the array configuration. Thus, I defined a symbol, "ArrayConfiguration" which  
only has options: ArrayElements ->120, TimeBandwidthProduct->20000,  
ElementSpacing->0.5, etc. Inside each of my actual functions, I then do...

   myFunction[a_,b_,opts___] := Module[
    	{K},
   	 K = ArrayElements /. {opts}, /. Options[ArrayConfiguration];
   	:
   	]
  

so if need be I can override the values and, otherwise, parameters set during my  
initial configuration hold.

I would thing a similar approach would hold for your problem. If you need to change  
the default on the fly, it should be easy with a SetOptions[].

Mark.
