All,

I would like to have some inputs available to many functions.  For example, I 
have coefficient for a term structure fit which I would like to make a 
available to total return functions.  Thereby eliminating the need to fit the 
same term structure over and over again.  However, I still reading and 
researching scoping.  My understanding is that I could fit the term structure 
and keep the coefficients in the global environment which would then make those 
coefficients available to all functions requiring a term structure object 
input.  Am I correct in my understanding.  What is the downside of environment 
global, if any?

Best Regards,
Glenn
