Anywhere to store non-volatile variables via code on PIC-MAXI-WEB?

[toozie21]

I have two variables that I would like to be persistent in my code, so I want to store them to non-volatile memory.  What is the best way to do this on this board without screwing up the data code or the web pages?

Currently I am trying to store using the XEEWrite commands and picking a place in memory that seems to be out of reach (so I won't cobble anything).  Is that the best way to do it on this 18F97J60?
