Re: select vs. if-elseif

[Joe Pluta <joepluta@xxxxxxxxxxxxxxxxx>]

I have a similar approach to Birgitta. If in my mind I am thinking "this 
is a condition where a small number of variables have specific states" 
then I use a select.  If it's a more complex set of business rules such 
as "if it's a non-taxable customer, do A, else if we're in a special tax 
facility do B, else if the item has special considerations do C" then I 
go with an If/Elseif stack.
