Subject: RE: Setting mutually inclusive vars

if your variables are related as you've shown, as well as the variables
coming in, you can use ranges and arrays--a range for your params and just
set array[i] in a loop. Also, I forget the syntax, but if you don't want to
use an array, you should be able to use dynamically named variables in a
loop and set them accordingly
