How do you create constants?

[Mikael Olofsson]

Can someone tell me why anyone would need true constants? 

I mean: 
I use variables that I leave unchanged throughout my code, but I have 
never felt that I would need them to be truly constant. I know which
variable to leave unchanged. I've never contributed to really large 
applications. Perhaps that's it?

If I ever was to develop anything large and complex enough that I could 
loose track of what to leave unchanged, I think I would feel confortable
enough with an instance of the write-once-read-many class that Christian
Tismer suggested this time (others have suggested it before). If I cannot 
remember to keep my hands off this only variable, then I should have my 
memory examined.
